地理国情普查成果应用探索——以广东省开发区土地利用强度评价为例

Application of the National Geo-information Survey Results——Taking the Evaluation of Land Use Intensity in Development Zone of Guangdong Province as an Example

土地资源是影响人类基本生活和发展的最主要的自然资源,由于其稀缺性,需要对土地资源进行合理开发和规划利用,土地利用强度是土地集约利用评价的一项重要指标。地理国情普查成果中的地表覆盖数据较传统土地调查数据具有客观、精细的特点,本文利用地表覆盖数据,以土地利用强度测算模型计算分析了广东省内近百个开发区的土地利用强度,为地理国情数据成果的应用做有益探索。

Land resources are the most important natural resources that affect the basic life and development of mankind.Due to its scarcity,land resources need to be properly developed,planned and utilized.Land use intensity is an important indicator of intensive land use evaluation.The land cover data in the National Geo-information Survey results are objective and fine features compared with the traditional land survey data.Based on the land cover data and the land use intensity calculation model,this paper calculates the land use intensity of nearly a hundred development zones in Guangdong Province,and makes a useful exploration for the application of the National Geo-information Survey results.
