摘要
自然保护区的综合效益的动态评价和分析对于效益的提升、管理的细化、历史的溯源等方向都具有极高的价值。以泉州湾保护区为例,通过因子筛选、指标计算、权重分析,以遥感、地理信息技术为基础,构建泉州湾保护区综合效益线性模型,并计算2014,2016,2019年综合效益。将综合效益结果进行空间统计分析,结果表明:泉州湾保护区综合效益在2014—2019年间上升26%,其中2016—2019年期间综合效益增长较快;泉州湾保护区效益热点区域主要为红树林和互花米草,效益冷点区域主要为水域和其他类型。
The dynamic assessment and analysis of the comprehensive benefits of nature reserves are of great value to the efficiency enhancement,management refinement and history tracing.Taking Quanzhou Bay as an example,through factor selection,index calculation and weight analysis,and based on remote sensing and geographic information technology,a linear model of comprehensive benefits of Quanzhou Bay is constructed,and the comprehensive benefits of 2014,2016 and 2019 are calculated.The results of spatial statistical analysis of comprehensive benefits data show that the comprehensive benefits of Quanzhou Bay in 2014-2019 increased by 26%,among which the comprehensive benefits increased more rapidly in 2016-2019;the hot spots of benefit in Quanzhou Bay nature reserve are mainly mangrove and Alternanthera,and the cold spots of benefit are mainly water areas and other types.
