摘要:

本文选取坡度、坡向、海拔、土地利用、交通、水资源、土壤质量等作为评价指标,利用GIS的叠置分析、缓冲区分析等空间分析技术对怒江峡谷区的泸水县人居环境适宜性进行了定量综合评价分析.评价结果表明,泸水县人居环境适宜区主要以带状形式分布在河流周围,其他区域只有零星分布,与泸水县人口分布的空间格局相吻合.泸水县人居环境状况与经济发展水平呈现明显的正相关性,人居环境评价值与各乡镇农民人均纯收入相关系数达到0.89,与各行政村农民人均纯收入的相关系数达到0.956.此外,本文还分析了泸水县各个乡镇的人居环境容量,表明泸水县已难以承载现有的人口.

Abstract:

The paper selects slope, aspect, altitude, land use, transportation, water resource and soil quality as evaluation indexes and assesses comprehensively suitability of residental environment in Lushui County of Nujiang Valley by using spatial analysis technical of GIS such as spatial overlay analysis, buffer analysis. Evaluation results: regions suitable for human inhabitance are distributed mainly around rivers in the form of strips, while others are scattered. There is a clear positive correlation between situation of residental environment and economic development, that is, the correlation coefficient between evaluation value of residental environment and township farmers’ per capita net income reaches 0.89, and villages farmers' per capita net income reaches 0.965 in Lushui. The article also analyzes residental environment capacity of all townships in Lushui, result shows the environment is difficult to carry the existing population in Lushui.

Key words: alpine valleys, geographic information systems, habitat environment, Lushui county
