山东省土地利用类型动态变化监测系统开发与验证

Development and Validation of Dynamic Monitoring System of Land Use in Shandong Province

摘要:

快速准确地区域土地利用分类是土地利用变化监测的重要部分。该文以山东省为例，使用Terra MODIS地表反射率产品（MOD09），根据山东省遥感影像在不同月份上地物反射率特征构建决策树，在VC平台上开发基于该决策树的针对MOD09数据的土地利用类型自动分类及变化分析的系统，对2000—2009年MOD09每月数据进行分类及其变化分析，并将结果与MODIS地表分类产品进行对比，验证了该系统的高效性和实用性。

Abstract:

Fast and accurate regional land use classification is an important part of land use change monitoring. In this paper, sdtting Shandong province as an example, by using the Terra MODIS surface reflectance rate product (MOD09), and based on different surface reflectance characteristics of remote sensing image in different months in Shandong province, decision trees have been set up. Based on the decision trees, on the VC platform, automatic classification and change analysis system of land use types based on the MOD09 data has been developed. By using this system, monthly data classification and change of MOD09 from 2000—2009 have been analyzed. It is showed this system has high efficiency and practices compared with the results of MODIS land surface classification of products.
