黄土高原地区土地利用程度分析

Analysis of the Degree of Land Use in the Loess Plateau

摘要: 对黄土高原地区土地利用程度分省进行计算分析，为黄土高原地区生态建设和进一步揭示人地关系及其相互作用提供理论参考。借助ArcGIS平台，利用5期土地利用/覆被空间数据集，基于土地利用程度综合指数模型，对黄土高原地区近20年土地利用程度进行分析。结果表明：黄土高原范围内河南省发展最快，其次为宁夏回族自治区、甘肃省、内蒙古自治区、青海省、陕西省，山西省属于调整期，发展相对缓慢。总体而言，黄土高原地区处于不断发展中，未出现明显的衰退现象。

Abstract: The calculation and analysis of the degree of land use in the Loess Plateau by province provides a theoretical reference for ecological construction in the Loess Plateau and for further revealing the relationship between man and land and their interaction. With the help of ArcGIS platform, the land use degree of the Loess Plateau in the past 20 years was analyzed based on the 5-phase land use/cover spatial data set and the comprehensive index model of land use degree. The results show that within the Loess Plateau, Henan Province has the fastest development, followed by Ningxia Hui Autonomous Region, Gansu Province, Inner Mongolia Autonomous Region, Qinghai Province, and Shaanxi Province. Shanxi Province is in the adjustment period and its development is relatively slow. In general, the Loess Plateau is in continuous development, and there is no obvious decline.
