在水土资源承载力评价中，由于指标过多，削弱了水土系统之间的耦合协调性。为解决这一问题，本文将区域水土资源承载力评价与系统耦合度的讨论相结合。以新疆为例，采用DPSIR概念模型作为评价水土资源承载能力的参考。建立了水土资源耦合模型，在分析农业、工业和生活用水需求的基础上，计算了新疆不同状态的水土资源耦合指数。通过对两个结果的叠加，可以看出水土资源的承载力和耦合是基本一致的。在水土承载力的基础上，进一步分析水土耦合的合理性，可以使研究结果更具实用性。
In the evaluation of water and soil resources carrying capacity,the coupling and coordination between water and land system is weakened because of too many indices.To solve this problem,this paper combines the discussion of regional water and soil resources carrying capacity evaluation and system coupling degree.For the example of Xinjiang,it adoptes the DPSIR conceptual model as a reference to evaluate the water and soil resources carrying capacity.It builds the coupling model of water and soil resources,calculates the coupling index of water and soil resources of different states in Xinjiang on the base of analysis on water demand of agriculture,industry and living.Through overlying two results,it shows that the carrying capacity and coupling of water and soil resouces are generally consistent.On the base of water and soil carrying capacity,further analysis of the rationality of water and soil coupling can make the research results more practical.
