摘要
促进贫困地区生态保护与经济建设协调发展是新时代国家扶贫开发的重要策略之一,是如期实现2020年全面建成小康社会的基础。以甘肃秦巴山贫困核心区为例,采用InVEST模型、市场价值法和影子工程法综合评估以水源供给、土壤保持、水质净化和固碳释氧为主的区域生态系统服务价值。运用参与式农村评估法,基于农户多维贫困测度指标体系,核算多维贫困指数。在综合测度两者耦合协调差异的基础上,分析其耦合协调差异的主要影响因素并针对性地提出分类指导策略。结果表明:(1)甘肃秦巴山贫困核心区25个特困片区生态系统服务价值为1 525.05亿元,其中,固碳价值最高。在各地类中,园地平均生态系统服务价值最大,耕地最小;(2)在25个特困片区的多维贫困中,基本物质需求相对充裕,健康状况贫困、文化教育贫困和社会关系贫困次之,经济收入贫困最严重;(3)由耦合差异分析可知,车拉、藏族等9个片区为生计资本落后型,经济收入、社会关系和文化教育是制约生态系统服务价值显化的主要因素。南阳、崖城等12个片区为生态资产落后型,林地、园地等高生态系统服务价值地类缺乏制约了多维贫困的持续改善。临江、新寨和大桥3个片区为协调发展型,仅理川片区为衰退失调型;(4)依据不同耦合差异类型及制约因素针对性地提出了分类指导策略,为精准扶贫战略决策提供科学参考。
It is one of the important strategies for poverty alleviation and development in the new era to promote the ecological protection and the coordinated development of economic construction in poverty-stricken areas,and it is also the base of the foundation of building a well-off society in an all-round way in 2020 as scheduled.Taking Qinba poverty stricken core areas in Gansu as a case,based on the InVEST model,market value method and shadow engineering method,the value of regional ecosystem services,mainly including water yield,sediment retention,water purification,and carbon fixation and oxygen release,were comprehensively evaluated.Based on the multidimensional poverty measurement index system of farmers′households(A),the multidimensional poverty index(B)was calculated with the participatory rural assessment method.On the base of the comprehensive measure of the coupling coordination differences between A and B,the main factors of the coupling coordination differences were analyzed,and the classification guidance strategy were put forward pertinently.Results show that:(1)the ecological services value of the 25 poverty sections in Qinba Mountain Poverty Stricken Core Areas in Gansu was estimated as 1525.05×108 Yuan.Among them,the carbon fixation value is the highest.The average ecosystem service value of the orchards is the highest,and that of the crop land is the lowest.(2)Among the multidimensional poverty factors of the 25 poverty sections,the poverty on income was the most serious,followed by the poverties on health status,cultural education and social relationship,and the poverty on basic material requirements was relatively low;(3)It can be seen from the analysis of the coupling coordination differences,9 sections such as Chela,Zangzu,etc.belong to the livelihood capital retarded type with income,social relationship and cultural education to be the main factors which restrict the manifestation of the ecosystem services.12 sections such as Nanyang,Yacheng,etc.are the ecological assets retarded type.In tho
