摘要
解决历史遗留问题是自然保护地整合优化的重要任务之一,同时也将引起自然保护地内的景观格局的变化,探讨自然保护地整合优化前后景观格局变化特征,对构筑山东生态格局安全具有重要意义。本研究以山东省自然保护地2020年封库数据为基础,从土地利用类型和景观格局两个尺度选取景观格局指数,借助ArcGIS和Fragstats 4.1软件,探讨全省自然保护地整合优化前后景观格局变化特征及其驱动力。研究结果表明,从景观类型水平看,整合优化后自然保护地农用地的斑块面积、空间连接度等显著降低,建设用地、林地景观类型破碎度和连接度降低;从景观格局水平看,调出矛盾面积的大小与景观格局变化贡献率呈正比,村庄面积虽小,但由于村庄分散性的分布特征导致其对景观格局破碎度的贡献率与城镇建成区和开发区基本一致。在六大类矛盾中,永久基本农田、人工集体商品林和矿业权的调出是影响景观格局变化的主要驱动因素。
To solve the problems left over by history is one of the important tasks for the integration and optimization of nature reserves,which will also cause changes in the landscape pattern of nature reserves.It is of great significance to reveal the change characteristics of landscape pattern of nature reserves before and after integration and Optimization for the construction of ecological pattern security in Shandong Province.Based on the data of nature reserves closed in 2020 in Shandong Province,the landscape pattern index was selected from the two scales of land use type and landscape pattern.Using the ArcGIS and FRAGSTATS 4.1 software,the change characteristics and driving forces of landscape pattern before and after the integration and optimization of nature reserves in Shandong Province were discussed.The results show that:from the perspective of landscape type level,the patch area and spatial connectivity of agricultural land of nature reserve land after integration and optimization are significantly reduced,while the fragmentation and connectivity of construction land and forest land landscape types are reduced;from the perspective of landscape pattern level,the size of conflict area is directly proportional to the contribution rate of landscape pattern change,although the village area is small,due to the scattered distribution of villages The contribution rate of landscape fragmentation is consistent with that of urban built-up area and development area.Among the six types of contradictions,permanent basic farmland,artificial collective commercial forest and mining rights are the main driving forces of landscape pattern change.
