基于自然和人文视角的甘肃省人居环境适宜性测度及阻碍诊断
Measurement and obstacle diagnosis of human settlement environment suitability in Gansu Province based on natural and humanistic perspectives
摘要
Abstract
Scientific measurement of the suitability of regional human settlement environments is a prerequisite for resolving conflicts between human-land and environmental carrying pressures.It is of great significance for achieving regional coordination and high-quality development.The study takes a 100 m×100 m grid as the basic unit,selects 12 indexes to construct a human settlement environment suitability evaluation model based on natural and humanistic perspectives,and uses the comprehensive weight method and obstacle model to measure the spatial distribution characteristics and obstacles of the human settlement environment suitability in Gansu Province.The results show that:(1)The suitability of the natural environment in Gansu Province is significantly higher in the eastern and central parts than in the northwest,and the suitability of the human environment shows a circle characteristic of gradually decreasing from the central city to the periphery.(2)The human settlement environment suitability index of Gansu Province ranges from 17.38 to 71.36.Spatially,it shows a distribution pattern of decreasing from the central urban area to the surrounding areas.The proportion of the five types of suitability is in the order of critical suitability>moderate suitability>general suitability>high suitability>unsuitable.(3)Disaster risk,terrain undulation,and vegetation coverage are the main obstacles to improving the suitability of the human living environment in Gansu Province,and the comprehensive obstacle degree of natural factors is 3.18%higher than that of human factors.These findings can provide decision-making support for guiding the rational population agglomeration,balanced regional environmental carrying capacity,and sustainable development in Gansu Province.关键词
