摘要
随着社会经济的快速发展,土地利用变化日趋剧烈,对生态系统及其服务价值产生重要影响,探究土地利用变化与生态系统服务价值之间的定量响应关系,对区域生态环境建设具有重要意义。以2010年和2016年滇池流域土地利用数据为基础,基于生态系统服务价值核算体系,定量评估了滇池流域土地利用变化及其转化对生态系统服务价值的影响。结果表明:(1)2010年和2016年滇池流域生态系统服务价值分别为688.16亿元和729.31亿元,6年间增加了41.15亿元。从各地类的生态系统服务价值来看,由大到小排序为林地>水域>耕地>建设用地>草地>裸地。(2)2010—2016年,滇池流域土地利用变化的剧烈程度由强到弱为建设用地>耕地>草地>林地>裸地>水域,耕地和建设用地的土地利用动态度较高,其中耕地面积减少了52.71km~2,建设用地面积增长了93.25km~2。(3)2010—2016年,滇池流域土地利用相互间的转化导致生态系统服务价值增加了3.88亿元,其中耕地、草地、城镇用地和裸地面积的变化增加了生态系统服务价值54.62亿元,林地和湿地面积的变化减少了生态系统服务价值50.74亿元。研究成果可为滇池流域协同推进经济社会高质量发展和生态环境高水平保护提供重要借鉴。
With the rapid development of social economy,land use types change dramatically which has an important impact on the ecosystem service value.Therefore,quantitatively estimating the impact of land use change on the ecosystem service value is of great significance to restore and construct regionally ecological environment.Based on the ecosystem service value accounting system and the land use data of Dianchi Lake Basin in 2010 and 2016,the influence of land use change and its mutual transform on ecosystem service value was evaluated.The results show that,the annual ecosystem service value of Dianchi Lake Basin grew from 68.816 billion to 72.931 billion Yuan during the period of 2010 and 2016.The order of the ecosystem services value from different land use types was:forest land>water area>cultivated land>built-up land>grassland>bare land.The order of the land use change degree was:built-up land>cultivated land>grassland>forest land>bare land>water area.The structure of land use changed significantly from 2010 to 2016.The type with the greatest dynamic degree was built-up land which had been increased by 93.25 km^(2).The following was cultivated land which had been decreased by 52.71 km2.During the period of 2010 and 2016,the ecosystem services value of Dianchi Lake Basin due to mutual transition among land use was increased by 0.388 billion Yuan.The ecosystem services value increased by 5.462 billion Yuan because of the changes in cultivated land,grassland,built-up land,and bare land,and decreased by 5.074 billion Yuan because of the changes in forest land and wetland.This study can provide an important reference for the coordinated promotion of high-quality economic and social development and high-level eco-environmental protection in Dianchi Lake Basin.
