川东地区生态系统服务价值时空演变及其驱动力分析
|
摘要
川东地区位于四川盆地东部,是长江上游重要生态屏障区。基于1990—2015年川东地区6期土地利用数据,采用空间统计分析法分析川东地区土地利用格局和生态系统服务价值时空演变特征,并结合社会经济因素,探究研究区生态系统服务价值时空差异驱动因素。结果表明:(1)川东地区主要土地利用类型为耕地和林地,土地利用综合活跃度低。(2)1990—2015年研究区生态系统服务价值持续增加,各土地利用类型对生态系统服务总价值的贡献率由大到小依次为林地(42%)、耕地(31%)、水域(22%)、草地(5%)和未利用地(0%);单位面积生态系统服务价值呈从东北、东南两翼向中西部地区逐级递减趋势。不同土地利用类型对生态系统服务价值具有不同程度的影响,其中林地、水域与生态系统服务价值高度相关。(3)生态系统服务价值时空差异主要驱动因素为农业人口数、人口密度、工业总产值和国内旅游收入。空间相关性分析结果表明,社会经济因素与生态系统服务价值变化率呈负相关关系,并且低-低和高-低型聚集在西部地区,低-高和高-高型聚集在南部地区。研究结果可为调控川东区域生态安全、优化土地资源和促进可持续发展提供科学依据。
The east region of Sichuan Province(C)huandong is a crucial ecological barrier in the upper reaches of the Yangtze River, which is of great significance. Using the dataset of 6 period from 1990 to 2015, both land-use change dynamics and value of ecosystem services were investigated by employing the methods of ArcGIS application and spatial statistics. Moreover, the driving factors were also researched in this study. It is found that:(1) Farmland and forest land were the main type of land use, which experienced low comprehensive dynamics.(2) The total ecosystem services value presented a trend of continuously increase. The greatest contribution of land use types to the total ecosystem services value was forestland(42%); and farmland(31%), water land(22%), grassland(5%) ranked 2~(nd), 3~(rd) and 4~(th), respectively. Unused land(0%) endured the lowest level. Besides, the ecosystem services value of unit area showed a declining trend from both northeast and southeast toward the central and west of the study area. Meanwhile,different types of land use had different impact on the ecosystem service value. The results show that both forestland and water land had strong positive correlation with ecosystem service value.(3) The main driving forces, which affected regional ecosystem service value, includes population density, rural population, industrial output and domestic tourism income. In addition, spational correlation analyais revealed that socio-economic factors had negative correlation with ecosystem service value. Low-Low and High-Low areas were clustered in the west, and Low-High and High-High areas were clustered in the south. Therefore, the results of this research can provide reasonable scientific basis on the ecological security and sustainable development for the east region of Sichuan Province.
