为探究三生用地类型的空间冲突水平对生态服务价值的影响以助力国土空间规划及生态环境保护,以德阳市罗江区为例,基于 2018 年 GF—1 号遥感影像数据,从"三生"角度出发对其生态服务价值进行评估.结合土地利用不同功能特点,构建三生用地分类体系,借助景观生态指数构建冲突指数模型,而后评估生态服务价值,以格网形式对三生用地类型的空间冲突水平及生态服务价值进行可视化表达,并通过相关性分析法探究空间冲突对生态服务价值的影响.结果表明:1)三生用地类型以生产生态用地为主,其次为生态生产用地及生活生产用地,生态用地仅占 5%左右.2)罗江区三生用地类型的空间冲突水平处于基本可控状态,主要为较弱和中等空间冲突,强空间冲突主要存于生活生产及生产生态用地,弱空间冲突主要存在于生活生产用地和生态用地.潜在冲突(弱空间冲突和较弱空间冲突)有转化为公开冲突(中等空间冲突和强空间冲突)的趋势.3)罗江区生态服务价值在布局上呈中间高四周低的特征,生产生态用地贡献最大,生活生产用地贡献为负.4)空间冲突指数与生态服务价值呈显著负相关,即空间冲突水平的变化对生态服务价值影响较大.
In order to explore the impact of the conflict level of production-living-ecological land type on the value of ecosystem services and to facilitate territorial spatial planning and ecological environmental protection,it took Luojiang district of Deyang city as an example to evaluate the ecological service value from the perspective of"production-living-ecological"based on the 2018 GF-1 remote sensing data.The production-living-ecological land classification system was constructed based on the different characteristics of land.The comprehensive index of spatial conflict evaluation model was constructed with the help of landscape ecological index,and then ecological service value was evaluated.The grid was constructed to realize the visual expression of the conflict level and ecological service value of"production-living-ecological land type,and the impact of spatial conflict on ecological service value was explored through correlation analysis.The results showed that:1)The land use type of production-living-ecological was mainly ecological land for production,followed by ecological-production and living-production land,and ecological land accounted for only about 5%.2)The level of spatial conflict in Luojiang area was basically controllable,which mainly consisted of the weaker spatial conflict and medium spatial conflict.Strong spatial conflict mainly existed in living-production land and production-ecological land,while weak spatial conflict mainly existed in living-production and ecological land.Potential conflicts(weak spatial conflicts and the weaker spatial conflict)tended to be transformed into open conflicts(medium spatial conflicts and strong spatial conflicts).3)The distribution of ecological service value in Luojiang district showed the characteristics of high in the middle and low around.The contribution of production-ecological land to ecological service value was the largest,and the contribution of living-production land was negative.4)The comprehensive index of spatial conflict was negatively correlated with the ecological service value,and the change of spatial conflict had a great influence on the ecological service value.
