西南低山丘陵区三生用地空间冲突对生态服务价值的影响研究
Impact of production,living and ecological land spatial conflict on ecological service value in the hilly region of southwest China
摘要
Abstract
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.关键词
