摘要/Abstract

摘要： 在Visual C++环境下,设计并实现了一个景观分析系统.该系统采用提取斑块边界象素集的方法,提高了斑块搜索的速度,而且提供了斑块间距离计算、相邻斑块间边界长度计算等景观分析功能.该系统被应用到北京西北郊的景观分析中.通过分析表明,该系统不仅能计算面积、周长、中心坐标和最近同类型斑块的距离等单个斑块指数,而且能在此基础上计算景观类型和整个景观层次上的各种指数,从而弥补了目前多数地理信息系统在景观分析应用中的不足.

Abstract: Because of the functions of Geographic Information System(GIS) being not satisfied to the requirements of landscape analysis,a landscape analysis system was designed with Visual C++ and demonstrated with remote sensing data.This system adopted the method f picking up patch boundary pixel set,improved the patch searching speed,and supplied some landscape analysis functions,such as the calculation of the distance between patches,and the boundary length of neighboring patch,which are not provided by current GIS.It was used to analyzed the landscape of suburbs in northwest Beijing,and the shortcomings of current GIS applied in landscape analysis were overcome.
