基于景观空间格局的公路景观定量评价指标体系

摘要

In view of the evaluation of environmental influence , based on the analysis of quality on highway landscape in China and the confusing content of evaluation, there is no uniform, normative and feasible method for quantitative evaluation. Through investigation, research, and practice of a large number of environmental highway landscape, the research method can be used for our reference landscape ecology. To explore the on landscape environment along the highway,this paper analyzd landscape spatial pattern in small scale, chose some index systems such as the number patches, size and scale of landscape spatial pattern ,the landscape crake index and landscape richness index to evaluate highway landscape environment quantitatively. Meanwhile, the paper used an evaluation index system, drew the support from ArcGis9.2 (geographical information system)and Fragstats3.0(The landscape pattern analysis software) in calculating , evaluating and analyzing the index of feature on the spatial pattern tourist highway landscape of Shen Nong-jia.%针对我国公路景观环境影响评价多以定性分析为主,评价内容庞杂无序,目前尚无统一、规范、切实可行的定量评价方法.通过对我国大量公路景观环境的调查、研究、探析与实践,借鉴景观生态学研究方法,探索在公路沿线景观环境研究范围内,从小尺度上分析景观空间格局,提出选取反映景观空间格局的斑块数量、大小、形状及景观破碎度、景观多样性等指标体系对公路景观环境进行定量评价.并采用该评价指标体系,借助地理信息系统ArcGis9.2及景观格局分析软件Fragstats3.0,对神农架旅游公路景观空间格局特征指标进行计算、评价与分析.
