以郑州市为例,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壤功能演变进行分析。研究发现,土壤功能的转化,导致大量具有生态功能的土壤丧失,产生了一系列生态环境效应:土壤多样性减少,土壤环境质量下降,生物多样性减少,水污染,地表水文变化,热岛效应明显。
Taking the Zhengzhou city as an example, compound method of RS, GPS technology and GIS space analysis technology with the correlation data were used to analysis change of suburb soil function. The results showed that the change of soil function causes massive lose of the ecology function of the soil and it caused the huge influence on the ecological environment. The soil,diversity soil environment quality and biodiversity drops,the water polluted. The city sewage processing success rate is low after processing rate,causes the rivers and streams water body and the farmland irrigation water is polluted. The surface hydrology change, the heat island effect is obvious.
