生态脆弱区土地退化与自然因子的耦合关系

Study on the Relationship between Land Degradation and Natural Factors

以吉林省西部为例,探讨土地退化与环境自然因子的耦合关系;利用ArcGIS9.2的空间分析模块,通过空间插值、统计分析、多因素叠置分析等多种空间分析方法,分析了地下水分布、地貌特征和土壤类型等几种主要的自然因子空间分布的差异及其对土地退化的影响方式、程度和范围。

Taking the western Jilin province for example, the spatial relationships between land degradation and natural factors were studied. Using the spatial analysis module provided by the ArcGIS 9.2, the difference of space distributing between several kinds of key natural factors, such as occurrence in groundwater, physiognomy charater, agrotype, and their influencing mode,degree,range on land degradation were arialyzed.
