Abstract:

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.

Key words: comprehensive benefits, dynamic evaluation, spatial statistical analysis, Gradient Boosting Machines, geographic information
