基于水资源承载力的新疆耕地后备资源开发布局研究

Research on the Layout of the Reserve Resources of Xinjiang Cultivated Land Based on Water Resources Carrying Capacity

结合新疆水资源利用情况与耕地后备资源分布状况,通过建立DPSIR指标体系利用均方差决策法计算出各指标权重值,从而测算出新疆14个地区的水资源承载力等级水平,结果表明东疆地区耕地后备资源水资源承载力水平高于南疆地区,且耕地后备资源分布与水资源承载力等级较为吻合,承载力水平高的地区应当优先开发耕地后备资源,承载力差的地区应当根据实际情况适度开发,合理开发利用每一寸耕地后备资源。研究结果有助于进一步科学规划水资源利用方式,合理开发耕地后备资源,缓解当前土地压力,改善耕地生态环境。

This paper is based on the water use and the distribution of cultivated land reserve resources. The mean square error decision method is used to calculate the weight value of each index by establishing the DPSIR index system. Then the level of ecological carrying capacity of 14 regions is estimated and the spatial layout of cultivated land reserve resources development in Xinjiang. The results show that the ecological carrying capacity of cultivated land reserve resources in Dongjiang is higher than that in southern Xinjiang and the distribution of cultivated land reserve resources is consistent with the ecological environment carrying capacity level. The high carrying capacity areas should give priority to the development of cultivated land reserve resources, the poor carrying capacity areas should be moderately developed according to actual condition, rational development and utilization of each inch of cultivated land reserve resources. The research results will facilitate the further scientific planning of water use methods and rational development layout of cultivated land reserve resources, relieve current land pressure and improve the ecological environment of cultivated land.
