| 摘 要： | 以鄯善绿洲为研究区,探讨乡村绿色廊道景观格局与生态功能。利用ERDAS 9.1软件处理影像数据,进行绿色廊道信息分类提取,区划矢量,建立拓扑关系,得出研究区廊道分布现状图;利用ArcGIS 9.2软件对景观结构进行分析。结果表明,研究区内4种类型廊道中,绿色农田防护廊道的长度和密度均最大,长度占到了绿色廊道总长度的49.63%,其次为灰色道路廊道和绿色道路廊道,分别占到26.46%和23.90%,蓝色渠系廊道只占到了0.01%,绿带几乎不存在。研究区内各种廊道,从连通度、线点率到环通度,都处于较低的阶段,致使绿色廊道的作用发挥不到最佳,因而需要在此基础上扩大绿色廊道宽度,增加其连通度,建立相对完善的绿色廊道网络体系,为当地能流、物流以及交通的流畅性提供保障。

| Abstract: | Taking Shanshan oasis as the study area,the landscape pattern and ecological function of village green gallery were discussed.Using ERDAS9.1 software processing satellite image,the classification and extraction of green corridor information,the division of vectors were carried out,thereby,established the topological relations and obtained the distribution status of corridor of study areas;using the ArcGIS9.2 software to analyze the structures of landscape.The results show that four types of corridors in the study areas,the length and density of the green farmland protection corridor are the largest,and the length occupy 49.63% of the total length of the green corridor,followed by the grey road corridors and green road corridors,and occupy 26.46% and 23.90% respectively,blue canal corridor only account for 0.01%,green belt almost does not exist.For various corridors of the study areas,from the point of connectivity,line rate to the ring-pass,at a lower stage,thereby,green corridor could not play the best role,therefore,based on this,we should expand the width of green corridor and increase its connectivity,establish a relatively perfect system of green corridor network for local energy flow,logistics and ensure the fluency of traffic. |
