Xinjiang is China's largest cotton and grape production base, but faces challenges like water scarcity, overuse of fertilizer and mulching films, and low resource use efficiency. This review summarizes crop production in Xinjiang from 2000 to 2020, including geography, climate, sowing structure, yield variations, and barriers to sustainable management. Based on our review, we identify potential technical solutions (i.e., precise irrigation and fertilization, organic fertilizer substitution, mulching film management, and suitability evaluation of arable lands) and policy support (i.e., national plans, laws, and financial support) required to overcome these barriers. Overall, the sustainable transformation of crop production in Xinjiang is a challenging yet promising endeavor. Implementing judicious to make full use of water, heat, and nutrition resources have great potential for achieving the synergies between high yield, resource utilization efficiency, and environmental benefits. The findings also have global implications for other regions dominated by arid and oasis agriculture. © 2025 The Author(s)

This article briefly introduces the development status quo of the natural resource survey management. There lack experiences on the effective working modes under the general trend of global integrated natural resources survey management. This article proposes the concept of survey point design, defines the survey indexes, constructs the technical system, and improves the map requirements based on the integrated survey and exploration of the county-level unit natural resources in Yicheng city, Hubei Province of China. The field study advances our understanding on the characteristics of background conditions of the natural resources of Yicheng city, analyzes and assesses the various resource endowments. The findings would serve the construction of China's ecological civilization and the unified management of natural resources in the new condition, and enrich our practical experiences on the dynamic integration of natural resources survey and geographical survey. It is verified that this exploration can represent the advanced concept of sample, and the technical system meets the applicability of most countries, which is worthy to be tested in countries with the needs of integrated resource management. © Geology Resource Management and Sustainable Development *** rights reserved.

The anti-skid pile is s an effective method for slope treatment. Analyzing its stress law and designing reasonable schemes are urgent problems that must be solved to guide slope prevention and control, and in this paper, combined with the original anti-skid pile reinforcement scheme, 5 pile-soil interaction models with different distance diameter ratios D/d are established. The anti-skid pile and slope are discretized, and the slope displacement and safety factor, pile stress and deformation, and soil arching effect between piles are numerically analyzed so as to optimize the design parameters of spacing diameter ratio of anti-skid piles. The results show that (1) the distance diameter ratio of anti-skid piles negatively correlates with the safety factor. When D/d>2.8, the slope safety factor is 2.011>2.0. (2) The peak shear force and soil arching effect of anti-skid piles are positively and negatively correlated with the distance diameter ratio, respectively. The reaction force of the anti-skid pile suddenly changes at the soil-rock interface about 10 m away from the pile top, and local reinforcement should be carried out when the anti-skid pile is designed and optimized. (3) Based on the analog data of displacement and safety factor changes, pile body stress, and soil arch stress between piles, and considering economic factors, the optimal distance diameter ratio D/d is determined to be 2.8-3.0. Compared with other methods, the optimization method proposed in this paper has reasonable theory and sufficient data. The research results will provide theoretical reference and engineering technical guidance for similar slope reinforcement with anti-skid piles, and have specific application and promotion value. © Published under licence by IOP Publishing Ltd.

In response to the frequent changes in land use and prominent conflicts between people and land in the Han River Basin, this study takes the Han River Basin as the research area, based on GIS technology, and uses the land use dataset from 2000 to 2022 to comprehensively utilize the land transfer matrix and standard deviation ellipse analysis to study the spatiotemporal characteristics of land use changes in the research area. The results show that from 2000 to 2022, the cropland area in the study area decreased the most, while the construction land area increased significantly;The spatial change of land use is inclined with the northwest to Dingnan direction as the main axis, concentrated in the southeast and central regions. The research results can provide scientific basis for the national spatial planning and sustainable development of central cities in the Han River Basin. © 2024 Proceedings of the 12th Academic Conference of Geology Resource Management and Sustainable Development, GRMSD 2024.

Water is the source of life, the foundation of ecology and the key to production. In Yicheng City, a typical county city in China's watersheds, the concept of water ecological carrying capacity and the assessment method are proposed by combining the general situation of the study area and the relevant research bases at home and abroad, taking into account the whole elements of natural resources. Determination of factor weights using a combined hierarchical analysis-entropy weighting approach. Deriving water ecological carrying capacity evaluation results suitable for adoption in rural China. Results and analysis of water ecological carrying capacity zoning and grading in Yicheng City. There are 223 village units in Yicheng City, and considering the spatial scarcity of the indicator factors, the study area is divided into four categories of village-level evaluation units, namely, the ideal carrying, preferable carrying, critical overloading and overloading. The proportion of the area is 9.56%, 25.24%, 46.65% and 18.55% respectively, providing scientific reference and data support for the construction of the "Thousand Villages Demonstration and Ten Thousand Villages Improvement" project and the realization of rural revitalization and sustainable development. © 2024 Proceedings of the 12th Academic Conference of Geology Resource Management and Sustainable Development, GRMSD 2024.
