摘要: 基于“三生”功能视角研究土地利用转型及其生态环境效应,是土地利用/土地覆盖变化研究的重要内容,可为区域“三生用地”优化提供支持。本文以辽宁省营口市为例,构建以土地利用主导功能为主的“生态生产生活”用地分类体系,采用修正的数量和空间分析模型分析“三生用地”转型的动态变化及地域类型,并采用改进的当量因子法分析生态系统服务价值的损益情况。结果表明:(1)2000—2015年,生态用地转移面积最大,转移活跃型分布在西南部和中北部;生活用地显著增加,增速较快,主要来源为生态用地和农业生产用地。(2)营口市生态系统服务功能总价值量先减后增再减,东南部高西部低;其变化呈现出“三区”的空间格局,其中,2000—2005年和2010—2015年东南部和中北部生态系统服务价值量明显减少,且其变化区域与生活用地新增活跃型的空间分布具有较强的一致性。

Abstract: Understanding land use transformation and its ecological effects based on “ecological-production-living” functions is an important issue of land use/land cover change, which can provide support for the optimization of “ecological-production-living” land use. We constructed a classification system of “ecological-production-living” land use mainly oriented by dominant functions of land use for Yingkou City. A modified quantitative and spatial analysis model was used to analyze the dynamics and regional types of “ecological-production-living” land use transformation, and adopted the improved equivalent factor method to analyze the profit and loss of ecological service value. The results showed that, during 2000-2015, the transferred area of ecological land was the largest, with the active types of ecological land being distributed in the southwest and central north of the city. The living land significantly increased with a high speed, being mainly transformed from ecological land and agricultural producing land. The total value of ecological service in Yingkou experienced a decreasing-increasing-decreasing process, and was higher in the southeast and lower in the west. The change of ecological service value presented a spatial pattern of “three regions”. During 2000-2005 and 2010-2015, the decreasing trend in southeastern and north central area was significant, consistent with the spatial distribution of newly added active type of living land.
