The Songhua River Pollution Control Project is one of the most significant water-related environmental pollution control schemes in Northeastern China. This paper details the requirements, architecture, and main components of an online river sudden pollution simulation system (RSPSS) for scientific planning and decision making for a complicated natural river network. On the basis of a service-oriented method and spatiotemporal simulation technology, the following components are developed: multi-platform, multi-level, dynamic, and flexible data services; task services that can be used by other online ArcGIS Server Silverlight Projects; and integrated third-party hydrodynamic and water quality models, which can simulate complex river networks under natural hydrological and climatic conditions online. With the RSPSS, spatial and non-spatial datasets and functions are seamlessly integrated from distributed sources by standard services. Thus, this system can support effective cross-regional and cross-departmental decisions. A study of a real-world implementation of the suggested system involving the historical sudden pollution of the Songhua River based on the RSPSS is also presented.

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. © (2014) 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. © (2014) Trans Tech Publications, Switzerland.

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

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.
