基于生态服务价值的产业园区生态控制线分析

Analysis of Basic Ecological Control Line of Industrial Park Based on Ecological Service Value

基于生态系统服务价值(ESV)法、影子工程法、替代成本法等生态服务价值计算方法,对广西钦州市某沿海产业园区土地利用状况进行生态服务价值分析,构建多目标规划模型,形成3个基本生态控制线方案情景,从生态服务价值评估角度研究分析园区土地利用变化对生态服务价值的影响,比选最优方案,从而划定园区的基本生态控制线。研究结果表明,正效应土地类型单位面积生态服务价值由高到低依次为红树林、水体、生态绿地、公共绿地,其中红树林面积对园区生态服务价值影响最大,各情景生态服务总价值由高到低依次为情景2、情景3、情景1。情景2可提升园区生态服务价值4513.67万元,调出建设用地仅0.57%,可实现在对产业园区发展影响最小的情况下最大程度保证其生态服务价值的目标。基于情景2划分产业园区基本生态控制线为一级管制区和二级管制区。研究评价了产业园区生态效益,也划分了产业园区生态空间格局,可为产业园区开展生态管控提供理论借鉴。

The ecosystem services value of land use in industrial parks in Qinzhou city of Guangxi Zhuang Autonomous Region has been analyzed based on the ESV method,shadow engineering project method,and replacement cost method.The multi-objective programming model was constructed to form three basic ecological control line scenarios.The impact of land use change on ecosystem service value was studied and analyzed.The optimal scheme was selected among the scenarios from the perspective of ecosystem service value evaluation.The results show that the ecological service value per unit area of positive effect lands were in the order of mangroves>water bodies>ecological vegetation>public green space.The mangrove area had the greatest impact on the ecological service value of industrial parks.The total value of ecological services in each scenario was scenario 2>scenario 3>scenario 1.Scenario 2 was the optimal scenario good for the improvement of ecological services of industrial park with an increasing value of 45.1367 million CNY by only reducing 0.57%of construction land.Based on this scenario,the basic ecological control line was dividing the industrial park into the first level control area and the second level control area.The value of ecological services of the industrial park under scenario 2 can be guaranteed to the maximum extent with the minimal impact on its development.The study scientifically predicts the ecological benefits,provides the basis for the ecological spatial pattern classification,and provides theoretical references for the ecological control and management of industrial parks.
