摘要
以甘南州为例,利用牧户调查数据,结合草地植被覆盖度,定量分析生态奖补对牧民生产生活和草地的影响。结果表明:1)生态奖补改善了牧民生活水平,当奖补收入每增加1万元时,日常消费增加0.46万元,宗教支出增加0.82万元;2)与以往研究不同,随着奖补收入的增加,牧户养殖牲畜数量增加,当奖补收入每增加1万元时,牲畜数量增加293.60个羊单位;3)奖补收入的增加也促使牧民的生产投入增加,奖补收入每增加1万元,租用草地和购买饲草料各增加1.05万元和0.39万元;4)由于生产投入的增加,生态奖补使草地实际载畜量降低,促进草地植被恢复,载畜量每公顷降低0.34羊单位,草地覆盖度提高2%。
Using a pastoral household survey and site-specific normalized difference vegetation index (NDVI) data,this study was conducted to investigate the impacts of the Grassland Ecological Compensation Policy on grassland and the livelihood of herdsmen in Gannan Tibetan Autonomous Prefecture,Gansu,China.The results showed that 1) the Grassland Ecological Compensation Policy increased the living standards of herdsmen;the consumption expenditures increased by 4.6 × 10^3 CNY and religious expenditure increased by 8.2 × 10^3 CNY for every 1.0 × 10^4 CNY increase in the total income of the Grassland Ecological Compensation Policy.2) In contrast to previous studies,the number of livestock animals increased with increase in the total income of the Grassland Ecological Compensation Policy;the number of livestock animals increased by 293.60 sheep units with every 1.0 × 10^4 CNY increase in the total income of the Grassland Ecological Compensation Policy.3) The increase in total income of the Grassland Ecological Compensation Policy also promoted the production input of herdsmen;the expense of renting grassland and purchasing forage increased by 1.05 × 10^4 and 3.9 × 10^3, CNY respectively.4) Because of increased production input,the Grassland Ecological Compensation Policy reduced the actual grazing capacity of the grassland,which promoted the restoration of grassland vegetation,and grazing capacity decreased by 0.34 sheep units·ha-1.The coverage of grassland improved by 2% for every 1.0 × 10^4 CNY increase in the total income of the Grassland Ecological Compensation Policy.
