【摘要】：基于顺德区1995—2011年的土地利用详查数据和社会经济统计数据,分析了全区土地利用变化和社会经济发展对生态系统服务的影响。结果表明:(1)顺德区的土地利用变化较快,耕地、水域面积减少,建设用地、园地面积增加,林地、草地以及未利用地面积相对稳定;(2)研究期间,顺德区的生态服务价值急剧减少,由1995年的7.68?108元减少到2011年的5.48?108元,16年间减少2.2?108元;(3)基于2000年不变价分析,发现人均生态服务价值与人均GDP和人口密度间均存在显著的负相关关系,相关系数分别为 0.817和 0.932;(4)生态服务价值与耕地和水域面积呈显著的正相关关系,相关系数分别为0.667和0.881;与园地、建设用地面积则呈明显的负相关关系,相关系数分别为 0.841和 0.906。
[Abstract]:Based on the detailed land use survey data and socio-economic statistics from 1995 to 2011 in Shunde District, the impacts of land use change and social economic development on ecosystem services were analyzed. The results showed that the land use of Shunde area changed rapidly, the area of cultivated land and water area decreased, the area of construction land and garden land increased, and the area of forest land, grassland and unused land was relatively stable during the study period. The value of ecological services in Shunde decreased sharply, from 7.68 yuan in 1995 to 5.48 million yuan in 2011. It was found that there was a significant negative correlation between the per capita value of ecological services and per capita GDP and population density, and the correlation coefficients were 0.817 and 0.932, respectively.) the value of ecological services was positively correlated with cultivated land and water area, respectively. The correlation coefficient was 0.667 and 0.881, respectively, and there was a significant negative correlation with the area of construction land. The correlation coefficient was 0.841 and 0.906 respectively.
