资兴市自然保护地空间冲突与重构研究

Research on Spatial Conflict and Reconstruction of Protected Natural Areas in Zixing City

自然保护地对生物多样性保护和环境质量提升有着重要作用,但其空间边界冲突导致管控不力,保护与发展的矛盾亟待破解。因此,应用GIS空间叠加分析技术对资兴市自然保护地空间格局及空间冲突特征进行了分析,并对其空间同质性展开综合评价。结果表明,资兴市域内6处自然保护地有5处存在一次或两次交叉重叠现象,面积达29577.30 hm2。因此,采用整合交叉重叠区域及边界、功能归并及管控分区等空间重构措施,将资兴市的自然保护地归并为2类4处,相比整合优化前,保护区总面积可增加0.02%。同时,应整合相应管理结构、实行差异化管控等以实现国土空间规划“一张图”管控。

Protected natural areas play an important role in biodiversity conservation and environmental quality improvement.However,its spatial boundary conflict results in a weak control,with the contradiction between protection and development to be further solved.Therefore,by using GIS spatial superposition analysis technique,an analysis has thus been made of the spatial pattern as well as spatial conflict characteristics of the protected natural areas in Zixing City,followed by a comprehensive evaluation of its spatial homogeneity.The results show that 5 of the 6 protected natural areas in Zixing City are characterized with one or two overlapping,covering a total area of 29577.30 hm^(2).Therefore,by adopting such spatial reconstruction measures as the integration of overlapping areas and boundaries,functional integration and management and control zoning,the protected natural areas in Zixing City are classified into two categories and four places,with the total area of the protected areas increasing by 0.02%compared with what prior to integration and optimization.Meanwhile,the corresponding management structure should be integrated and differentiated management and control should be implemented to realize the"one map"management and control of land and space planning.
