摘要
景观指数是衡量区域景观质量重要参数,也是进行区域生态设计与规划的重要依据。针对基于传统的已有的矢量地图信息源及Excel、SPSS软件在景观指数计算中存在不足和不便之处,研究了在ENVI 4.2下,基于高分辨率SPOT-5遥感影像的自动景观分类及Fragstats3.3软件支持下的景观指数的自动提取的计算方法,以屈原农场为例进行了实验研究,制作了景观现状图和计算部分景观指数。试验表明:该方法对景观信息的获取效率高、时效性强,是区域景观管理、设计与规划的有效技术手段。
The landscape index is an important parameter of judging landscape＇s quality, is also the importance basis of carrying out the design and planning of regional ecology. To the place of insufficient and short of the traditional vector graph of geography and computing of landscape sight in Excel or SPSS remote sense image, the article has studied a method of landscape computing, it base on automatic classification of landscape of high resolution SPOT-5 remote sense image in ENVI 4. 2 and the extract automatically of landscape exponent in Fragstats3. 3 software, The experiment has studied Quyuan farm and gained landscape current situation map and information of partial landscape exponent, the experiment show that the gain of landscape information is high efficient , timeliness is strong , by the method , it is a effective technology means of landscape manages,designs and planning.
