石漠化治理区社会经济效益定量评价——以贵州省六枝特区为例

Quantitative evaluation of social and economic benefits in the rocky desertificated management district:A case study in Liuzhi special region,Guizhou Province

为了解决我国西南地区石漠化治理过程中,社会经济效益难以量化的现状,以六枝特区为例,从土地利用、产业结构、总产值增长率、产值结构、消费结构、人均纯收入增长率6方面,选取16个因素作为评价指标,构建石漠化治理区社会经济效益定量评价体系。借助层次分析法确定权重,运用递阶多层次综合评价法建立评价模型,对研究区社会经济效益进行定量评价。结果表明:土地利用、产业结构、总产值增长率、产值结构、消费结构、人均纯收入增长率等指标的评价指数均随时间呈上升趋势,土地利用指标指数从0.807 4上升到0.862 3;产业结构指标指数从0.470 8上升到0.598 6;总产值增长率指数从0.568 4上升到0.804 8;产值结构指数从0.625 6上升到0.599 9;消费结构指数从0.666 1上升到0.770 7;人均纯收入增长率指数从0.380 9上升到0.733 2。六枝特区治理工程带来的社会经济效益评价指数呈逐年上升趋势,从2008年的0.533 3上升到2013年的0.672 0,石漠化治理工程已见成效。

To solve the difficult of social and economic benefit evaluation in the process of controlling rocky desertification in southwest of China,a case study was conducted in Liuzhi special region.This paper established the quantitative evaluation system of social and economic benefits in the rocky desertificated management region based on 16 factors as evaluation index from 6 aspects which were land utilization,industrial structure,output growth rate,output value structure,consumption structure and growth rate of per capita net income.Social and economic benefits were quantificational evaluatedby the analytical hierarchy process to determine weights and hierarchical multi-level comprehensive evaluation method to establish evaluation model.Results showed that the evaluation indexes of land utilization,industrial structure,output growth rate,output value structure,consumption structure and growth rate of per capita net income increased as time went on.In detail,land utilization index increased from 0.807 4 to 0.862 3,industrial structure index increased from 0.470 8 to 0.598 6,output growth rate index increased from 0.568 4 to 0.804 8,output value structure index increased from 0.625 6 to 0.599 9,consumption structure index increased from 0.666 1 to 0.770 7 and growth rate of per capita net income index increased from 0.380 9 to 0.733 2.The socio-economic evaluation index in Liuzhi management region increased from the 0.533 3 in 2008 to 0.672 0 in 2013,which indicated the rocky desertification control project was effective.
