摘　　要：选取广东省29个国家级开发区作为研究对象,通过2017、2018年度高分辨率遥感影像,利用ArcGIS软件对开发区地表覆盖进行全面采集。通过计算各开发区内部2017—2018年度地表覆盖程度指数以及不同地表覆盖类型变化动态度指数,对开发区内部地表覆盖空间演变进行分析,得到各开发区当下开发程度和速度,掌握开发区利用情况。结果显示,2017—2018年广东省国家级开发区整体地表覆盖程度指数呈上升趋势,增加量为4. 491 2,说明开发区整体地表覆盖处于发展期,主要表现为构筑物和人工堆掘地面积的增加。从不同类型地表覆盖动态度看,荒漠与裸露地表和人工堆掘的动态度较高。29 nationd-level development zones in Guangdong province were selected as the research objects.Based on high-resolution remote sensing images in 2017 and 2018,the land cover of development zones were collected.The intensity and speed of utilization in different zones could be revealed by calculating the intensity index and dynamic degree index.The results showed that the overall intensity index of national level development zones in Guangdong province was on the rise from 2017 to 2018,with an increase of 4.49,indicating that the development zones were in the period of development.In terms of the dynamic degree index of land-cover of land covers,the bare land and artificial heap excavation had higher dynamic attitude.

关 键 词：国家级开发区 地表覆盖程度指数 地表覆盖变化动态度
