摘　　要：本文从地形、气候、水文、地被和自然灾害5个方面构建生态环境宜居性评价模型,对浙江省生态环境宜居性空间格局、地域特征及其与人口分布的关系进行了定量综合评价,以期为协调浙江省人口和生态环境之间的关系,促进人居环境科学发展和城市可持续发展,以及确定省内差别化的区域发展定位提供管理与决策参考。研究表明:浙江省生态环境宜居性总体分布态势呈现出由西南地区向东北地区,山地向丘陵、河谷、平原递减的趋势。生态环境宜居性程度分区中,低宜居性区覆盖人口最多、人口密度最高,较高宜居性区覆盖面积最广。浙江省生态环境宜居性与人口密度之间存在对数函数关系,二者的曲线拟合度R2值为0.7547;但是对数函数的系数为负数,说明浙江省生态环境宜居性与人口密度之间存在较强的负相关关系。浙江省人口分布对生态环境宜居性指数并不存在明显的响应,大部分人口分布于生态环境宜居性指数较低的地区。浙江省需注重城市生态环境保护与环境污染治理,最大限度地实现人口分布与生态环境宜居和谐共生。Suitable eco-environment for human settlement plays a significant role in harmonious development between social-economic systems of human society and natural ecosystems. After selecting terrain,land cover,climate,water condition and natural disaster as evaluation factors,this study established an eco-environmental livability index（ ELI） model and evaluated the eco-environment livability for human settlement in Zhejiang Province based on GIS. The results indicated that there was obvious spatial difference in the distribution of population density in Zhejiang Province. The sparsely-populated areas were mainly distributed in the northwest and southwest mountainous areas,whereas the densely-populated areas were mainly distributed in central plains areas,eastern coastal areas and Jinqu Basin. In addition,the results also revealed that ELI of Zhejiang Province generally decreased from the southwest to the northeast and from mountainous and hilly areas to plains and valleys,which reflected regional differences of eco-environment livability of human settlements in Zhejiang Province. Among divisions of eco-environment livability,the lowest livability region comprised the most populous areas,accounting for about 28. 71% of the total population. The higher livability region encompassed wide land areas,accounting for about 26. 18% of the total area. Additionally,ELI of Zhejiang Province was correlated with population density（ R2= 0. 7547）,while the coefficient of function was a negative number,which indicated that the eco-environment livability and the population distribution were negatively correlated. Furthermore,the population distribution of Zhejiang Province did not have an obvious response to eco-environment livability and most people lived in the lower eco-environment livability region. This was not consistent with the result of previous researches. The main reason for this was that the distribution of terrain conditions was not consistent with land cover,climate and hydrology conditions in Zhejiang Province.T
