河北省坝上地区沙化背景分析及景观生态对策——以沽源县为例

An Analysis of Desertification Background and Landscape Ecology Countermeasures--With Guyuan County as an example

经过实地考察并结合遥感图像处理,本文从地质地貌、气象、人类活动三方面分析了沽源县沙化背景,在此基础上运用景观生态学理论把本区划分为沿坝、沿边、中部农田草地三个景观生态系统,并分别提出了各生态系统的土地规划利用方向。

Through on-the-spot investigation and in connection with the processing of remote sensing images, this article analyzes the desertification background within Guyuan County in terms of geology and landscape, meteorological phenomena, and human activities. Using the theory of landscape ecology, the paper classifies the county into three landscape ecology systems, and discusses the direction of land planning and utilization of each system.
