基于指标体系的新疆农业水资源高效利用评价
|
摘要
农业水资源高效利用评价是水资源评价的基础与前提条件,该文结合新疆地区的水资源特点,从可持续发展的角度出发,构建新疆地区农业水资源高效利用评价指标体系,进行农业水资源高效利用评价内涵与原则的研究。在评价方法上,选择熵值法求权重并进行赋权,同时建立投影模型进行农业水资源高效利用评价。结果表明,从整体的综合评价结果来看,新疆地区的农业水资源高效利用率总体偏低,评价结果符合客观事实,对提高水资源优化配置与高效利用提供了科学依据,并对今后该地区的水资源系统规划产生了宏观的使用效益。
The evaluation of the efficient use of agricultural water resources is the basis and prerequisite for water resources evaluation. The research on the connotation and principle of the evaluation of the efficient use of agricultural water resources is conducted. Based on the characteristics of water resources in Xinjiang,the agricultural water in Xinjiang is constructed from the perspective of sustainable development. The evaluation index system for efficient use of resources,in the evaluation method,the entropy method is chosen to find the weights and weighted,and the projection model is established to evaluate the efficient use of agricultural water resources. The results show that, from the overall evaluation results, the overall utilization efficiency of agricultural water resources in Xinjiang is generally low,and the evaluation results are in line with objective facts,providing scientific basis for improving the optimal allocation and efficient use of water resources,and for the future the water resources system planning has produced macro use efficiency.
