摘要
景观指数是衡量区域景观质量的重要参数,也是进行区域生态规划、管理和恢复的重要信息依据。针对传统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的不足和不便之处,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。实验表明:该方法对景观质量的评价信息获取效率高、时效性强,通过快速分析与评价手段,可以大大地促进区域进行规划、管理和恢复的科学性和可操作性。
The landscape index is an important parameter of judging landscape＇ s quality, and the importance basis of carrying out the design and planning of regional ecology as well. Because of the insufficient and short of the traditional vector graph of geography and computing of landscape sight in Excel or SPSS remote sense image, in this paper a method of landscape computing, is studied based 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 was carried out in QU Yuan farm and gained landscape current situation map and information of partial landscape exponent, the experiment shows that method used to the gain of landscape information is high efficient, timeliness is strong, which is a effective technical means of landscape manages, designs and planning.
