ABSTRACT

Human activity intensity evaluation is the basis of analyzing the impact of human activity on the region. With increasing scale and quantity of human activity, the impact on the ecological environment is also more and more serious. The multifactor evaluation model of human activity intensity is established by determining the classification standard index. Firstly, population density, gross domestic product (GDP) per capita, mining points, construction land ratio and land utilization ratio are selected as quantitative indexes. Secondly, the weights of evaluation indexes are obtained by using objective valuation method. Further work, the quantitative evaluation model and systematic analysis of human a`ctivity intensity for Ji’nan city are established by multifactor method. The results show that the areas with the highest intensity of human activities are mainly distributed in Ji’nan urban area, the areas with higher intensity are mainly distributed in some towns of Licheng District and the urban areas of counties and cities, the areas with middle intensity are mainly distributed in the areas near Ji’nan urban area and counties, and the areas with lower intensity are mainly distributed in some areas far away from counties and cities. Quantitative evaluation of human activity intensity is helpful to investigate the changes of ecological environment.

摘要

人类活动强度评价是分析人类活动对区域影响的基础。随着人类活动规模和数量的增加，对生态环境的影响也越来越严重。通过确定分类标准指标，建立了人类活动强度的多因素评价模型。首先选取人口密度、人均国内生产总值(GDP)、采矿点、建设用地比例和土地利用率作为量化指标。其次，采用客观评价方法获得评价指标的权重。进一步的工作，采用多因素方法建立了济南市人类活动强度的定量评价模型和系统分析。结果表明，人类活动强度最高的地区主要分布在济南市区，强度较高的地区主要分布在历城区部分城镇和县市市区，强度主要分布在靠近济南市区和县城的地区，强度较低的地区主要分布在远离县城的一些地区。人类活动强度的定量评价有助于研究生态环境的变化。强度中等的地区主要分布在济南市区和县城附近的地区，强度较低的地区主要分布在远离县城的一些地区。人类活动强度的定量评价有助于研究生态环境的变化。强度中等的地区主要分布在济南市区和县城附近的地区，强度较低的地区主要分布在远离县城的一些地区。人类活动强度的定量评价有助于研究生态环境的变化。
