Based on TM remote sensing image and topographic map, the spatial information of landscape pattern was extracted in Hulunbeier steppe in 1995, 2000, 2005 and 2010. With the principles and methods of landscape ecology, landscape fragmentation index, division index, dominance index and fragility index were selected to construct the ecological safety index which was used to quantitatively analyze the dynamic changes of landscape pattern and elucidated ecological safety status in study area. Result showed that the overall landscape tended to become fragmentized and complicated with the total number of patches increasing in the study area from 1995 to 2010. The ecological safety index of landscape types can be classified into four grades, grassland > unused land, wood land > water body, crop land > construction land. Overall, the regional ecological safety status got worse with the ecological safety index of natural landscapes decreasing and the ecological safety index of artificial landscapes increasing. In particular, the area of construction land had a continuous increase with a higher growth rate (7.41% per year during 2005~2010), which will be unfavorable to regional ecological safety as the biggest potential risk. © (2013) Trans Tech Publications, Switzerland.

Based on the remote-sensing data and ground data, this study is conducted on the ecosystem function of Yiwulvshan National Nature Scenic Area(hereinafter as "Yiwulvshan Scenic Area") from 2000 to 2010 with the GIS(geographic information system) and RS(remote sensing) technology, so as to provide reference for better environmental protection of the scenic area. It is shown from the results that there is no obvious change of land use in Yiwulvshan Scenic Area;while the capacity for soil and water conservation is slightly improved mainly due to increase of vegetation coverage;the vegetation net primary productivity declines somewhat about 5.27% in past 10 years;and biodiversity is slightly increased. As a whole, the ecosystem function of Yiwulvshan Scenic Area basically kept stable in the past 10 years, which indicated that the existing regulations can effectively protect the ecological function of the Scenic Area.

In this paper, 2000-2010 NDVI data of Liaohe Basin is obtained with the RS technology;the distribution map of precipitation and air temperature in Liaohe Basin is generated by the GIS technology, and then the temporal and spatial vegetation variation of Liaohe Basin and its relation with climate changes have been studied by means of raster data spatial analysis, correlation analysis and multiple regression analysis, so as to provide a scientific basis for ecological environment protection, planning and development of Liaohe Basin. It is shown from results that: 1) From 2000 to 2010, the vegetation coverage increased significantly;which presents a gradual decrease from east to west on the spatial distribution;2) For the temporal distribution, the precipitation presents a fluctuant upward trend;while temperature is fluctuated significantly with a slight decrease. For the spatial distribution, precipitation decreased gradually from the east to west, while temperature rises from the northeast to southwest;and 3) Vegetation coverage of Liaohe Basin is positively related with precipitation and temperature in the temporal and spatial distribution, but not significantly, it is indicated that, except for the meteorological factors, the artificial impact and other factors, such as land use, played an important role to vegetation variation of Liaohe Basin in the recent 10 years. However in terms of two influence factors of precipitation and temperature, the former has significantly contributed to NDVI change of Liaohe Basin.

Wetland ecosystem occupies an important position in the global carbon cycle with a strong ability of carbon storage and fixation. On the basis of field investigation and laboratory measurement, in the paper, the standing biomass and primary production of wetland Phragmites australis in Baiyangdian were study, and its ability of carbon storage and fixation in accordance with the principle of photosynthesis was measured, and then the potential ability of carbon storage from the perspective of efficiency for solar energy utilization was discussed. The results show that carbon storage of wetland Phragmites australis is large in Baiyangdian with 5.81 kg • m -2 , 7.14 kg • m -2 and 8.72 kg • m -2 respectively; carbon fixation is also very large with 2.54 kg • m -2 , 3.12 kg • m -2 and 3.81 kg • m -2 respectively. In addition, the underground biomass is larger than the aboveground biomass, and the ratio of the two is 2.38-3.30 with the average of 2.90. The underground carbon storage is nearly 3 times as much as the aboveground carbon storage. Wetland Phragmites australis in Baiyangdian has a strong ability of carbon fixation with 1.17 kg • m -2 • a -1 , 1.49 kg • m -2 • a-1 and 1.76 kg • m -2 • a-1 respectively, which is 1.7-3.4 times as much as the average ability of carbon fixation of the national terrestrial plants and 2.0- 4.0 times of that of the global plants.

Natural iron oxides nanomaterials have important roles in biogeochemical processes. In this study, the effects of pH, natural organic matter, and cations on aggregation and sedimentation of natural goethite and artificial Fe3O4 nanoparticles in water were investigated to learn more about the environmental behaviors of engineered and natural nanomaterials and how they differ. In addition, a novel extended DLVO theory that considered steric, gravitational, and magnetic attraction forces concurrently was specifically developed to provide mechanisms explanations. Specifically, Fe3O4 NPs were more likely than bulk goethite to aggregate (because of magnetic attraction interactions) at low HA concentrations and disperse at high HA concentrations. Besides, goethite was less prone to settle with the same concentration of NaCl than Fe3O4 NPs, but the opposite trend was found for the same concentration of CaCl2 because of the difference in maximum net energy (barrier) and strong Ca2+ bridging effectiveness of goethite in CaCl2 solution. Statistical models were established to evaluate colloidal stability of the particles. XPS and molecular dynamics simulation results suggested that ions were adsorbed onto particles via ionic polarization and that the binding free energies at high coverage followed the order Ca2+ > Na+ > Cl- and presence of cation bridging between particles. © 2022, The Authors.

On the surface of hyperspectral data of remote sensing to estimate grassland biomass, the soil water content, organic matter content important impact on the model application. An ASD Fieldspec 3 spectroradiometer was used for spectral measurements of the Hulunbeier Meadow Steppe, Inner Mongolia, China, in late July, 2013. Ground spectral models were built to estimate the Above-ground Net Primary Productivity (ANPP) at the peak of the growing season from the Correction Normalized Difference Vegetation Index (C NDVI ) measured in the field. The SPSS software were used to assess relationships between ANPP and C NDVI . Based on the coefficient of determination (R 2 ), quadratic model (R 2 =0.808) and exponential model (R 2 =0.717) were batter than others. Error analysis shows that the linear equation has the biggest standard error of the prediction (SE = 82.42g/m 2 ), the logarithmic curve equation has the smallest SE (SE=18.59g/m 2 ). After considering all factors, a quadratic equation between ANPP and C NDVI (ANPP=3738.048 NDVI MODIS 2 -259.1588NDVI MODIS +1309.847, R2=0.808, SE=66.25g/m 2 , MEC=0.820, P

The expansion of linear infrastructure represents a significant threat to biodiversity. Given the paucity of research on the systematic conservation of species diversity, it becomes imperative to conduct extensive research on the utilisation of wildlife passages. We selected typical areas within the Xinjiang protected area system for the investigation and monitoring. This involved evaluating the utilization of passages during different periods and identifying the main influencing factors to improve the utilization rate of passages. The objective was to provide basic data support for revealing the interaction mechanism between linear infrastructure such as roads and fences and wild animal activities. The results indicated that 32 species of wild animals were photographed, including 13 species of birds representing 8 families from 5 orders, and 19 species of mammals representing 10 families from 5 orders. The relative abundance index of Cetartiodactyla and Perissodactyla wild animals, including bharal, goitered gazelle, asian wild ass, and wild bactrian camel, was notably high. Utilization rates of the passage at night were significantly higher than at other periods. The wild animals exhibited the highest selectivity for the underpass passage (JSInight=4.08) of the Kalamaili Mountain Ungulate Wildlife Nature Reserve and the fenced passage reserved of the Bosten Lake Scenic Area (JSInight=4.19). Wild animals exhibited a strong preference for the passage during sunrise and sunset, with 86.86% of the monitored plots JSIsunrise>0 and 91.30% of the monitored plots JSIsunset>0. The density of linear infrastructure was a key factor influencing passage utilization, with a significantly negative correlation. This was followed by the intensity of human activities. Furthermore, the larger the passage size and the higher the vegetation coverage, the higher the utilization rate of wildlife passages. It is recommended that the spatial layout and design of wildlife passages be optim
