摘要
以贵州省某典型灌区为例,利用系统动力学、压力-状态-响应模型等,建立水土资源承载能力的评价方法.验证分析显示,灌区 1996、2004、2012 和 2020 年的水土资源承载状态分别为轻度、逼近、逼近和平稳.结果表明,研究提出的评价体系对灌区水土资源承载能力分析具有合理性和可行性,灌区的水土资源承载状态在空间中为积极性变化,但变化速度减缓,严峻以及轻度承载面积在空间分布中逐渐向盐碱化等趋势过渡.
Abstract
The study takes a typical irrigation district in Guizhou province as an example,and utilizes system dynamics and pressure-state-response modeling to establish an evaluation method for the carrying capacity of soil and water resources.The validation analysis shows that the carrying status of soil and water resources of the irrigation area in 1996,2004,2012 and 2020 are mild,approaching,approaching and stable,respectively.The results indicate that the evaluation system proposed in the study is reasonable and feasible for analyzing the carrying capacity of water and soil resources in irrigation areas.The carrying status of water and soil resources in irrigation areas shows positive changes in space,but the rate of change slows down,and the severe and mild carrying areas gradually transition towards salinization and alkalization in spatial distribution.
