城市化、工业化的发展和城市人口的高度集中对土壤的水源循环功能产生了深刻和持久的影响,主要表现为土地利用的不合理引起的土壤封闭过度、地下水位降低、水源污染等,因此需要合理的国土规划以达到优化利用。但土壤水循环功能价值由于量化研究比较少,其重要价值难以货币形式直观表达出来,很容易造成实际土地利用中的低估和忽视。文章选取郑州市为研究区域,通过市场法、价格替代法和实测数据构建土壤水源循环功能货币化体系,利用地理信息系统提出研究地区土壤功能需要保护和恢复的目标,从而提高保护意识,形成土地利用规划的参考。
Urbanization, industrialization and high concentration of urban population have a profound and lasting impact on the water cycle function of the soil, mainly due to over-closed soil, lower groundwater level and water pollution caused by unreasonable land use, Reasonable land planning in order to achieve optimal utilization. However, due to the small amount of quantitative research on the function value of soil water cycle, its important value is hard to be directly expressed in the form of money, which can easily lead to underestimation and neglect in actual land use. This article chooses Zhengzhou as the research area, constructs the monetization system of soil water cycle through market method, price substitution method and measured data, and puts forward the goal of studying and protecting the soil function in the area by using the geographic information system so as to raise the protection consciousness and form the land Use planning reference.
