【摘要】：以重庆市大都市区为研究区,以2003年和2013年的土地利用数据为基础,探讨不同地域单元生态系统服务价值时空变化,采用熵值法对社会经济综合发展水平进行衡量,并运用空间自相关模型分析其社会经济综合发展水平和生态系统服务价值之间关系。结果表明:研究期间,生态系统服务价值增长100.98亿元,空间分布表现为东南高西北低,区域中部主城区为低值聚集区的基本形态;社会经济综合发展水平整体提高,空间分布以主城核心区为中心逐渐向外降低;社会经济综合发展水平与生态系统服务价值呈现空间负相关关系,其中高—高聚集区和高—低聚集区分布在区域中部的主城区,低—低聚集区分布在区域西部,低—高区域分布在东南部。10a间,高—高聚集区范围扩大,高—低聚集区和低—低聚集区范围缩小,低—高聚集区无明显变化。
[Abstract]:Based on the land use data of 2003 and 2013, the spatio-temporal changes of ecosystem service value of different regional units were discussed in Chongqing metropolitan area, and the comprehensive development level of social economy was measured by entropy method. The spatial autocorrelation model is used to analyze the relationship between the level of social and economic development and the value of ecosystem services. The results showed that the value of ecosystem services increased by 10.098 billion yuan during the study period, the spatial distribution was high, northwest and low in the southeast, and the main urban area in the middle of the region was the basic form of the low value accumulation area. The overall level of social and economic development has been improved, and the spatial distribution has gradually decreased outwards with the core area of the main city as the center; The comprehensive level of social and economic development is negatively related to ecosystem service value, in which high-high concentration and high-low concentration areas are distributed in the main urban areas in the middle of the region, and low-low accumulation areas are distributed in the west of the region Within 10 years, the range of high and high concentration areas was enlarged, the range of high and low accumulation areas and low-low accumulation areas was reduced, and the low-high accumulation areas had no obvious change.
