摘 要: | 【研究目的】为探讨郑州市郊区土地利用变化及其对土壤功能的影响;【方法】以郑州市及郊区为例,通过野外调查数据、遥感数据和社会经济统计数据,并采用RS和GPS技术集成方法结合GIS空间分析技术对郑州市及郊区土地利用变化及其对土壤功能影响进行分析;【结果】研究发现,1988年至2002年,各类用地变化率分别是-25.71%,-31.21%,-39.20%,-30.46%,-57.59%,148.35%,91.72,50.87%,-16.93%,-56.44%。1988—2002年,郑州市城市、居民点、交通用地不断增加,而水浇地、旱地、菜地等农业用地不断减少,这导致土壤生产功能与土壤生态功能、承载功能相互转换,大量的具有生产功能的土壤资源演变成承载功能;【结论】随着土地利用变化的发生,必然导致大量的土壤生态功能将会永久消失,将会产生一系列生态效应。

Abstract: | OBJECTIVE]to find the change of land use in Zhengzhou suburb and its effect on the soil function;METHOD]take and the suburb area of Zhengzhou as an example,studied the change of land use and the effect to suburb soil function;RESULTS]results showed that,1988to2002,the proportion of all the land use is-25.71%,-31.21%,-39.20%,-30.46%,-57.59 %,148.35%,91.72,50.87%,-16.93%,-56.44%.much land for agriculture become the land for construction,the change between soil production function and ecological functions,carrying conversion function,great deal of the production function of soil resources into carrying function.CONCLUSION]because of the change of land use,much Soil ecological functions will disappear,it will produce a series of ecological effects. |
