两轮奖补政策草原生态效益评价—以甘南州美仁草原为例

以甘南州美仁草原为例,通过甘南州草原监测数据及牧户调查问卷资料,对两轮草原生态奖补政策实施效果进行了分析。结果表明,随草原奖补政策的实施,甘南州草原平均年降水量、最低气温、最高气温、平均气温呈升高趋势,草原植被盖度、草群平均高度和产草量呈增长趋势,增加了草原可利用面积和草原理论载畜量。甘南州两轮草原生态保护补助奖励政策的实施,对改善草原气候、提高草原产草量、增加草原可利用面积和提升草原理论载畜量有明显的促进作用,取得了显著的生态效益、经济效益和社会效益。

The results showed that the average annual precipitation, minimum temperature, maximum temperature, and average temperature of the grasslands in Gannan prefecture showed an increasing trend, while the vegetation coverage, average height of grass groups, and grass yield of the grasslands also showed an increasing trend, the available area and theoretical livestock carrying capacity of the grasslands increased after implementation of the two-round bonus policy. Overall, our findings revealed that significant ecological, economic and social benefits had been achieved, including improvement climate, increasing grassland yield, usable grassland area andStheoreticalSlivestock-carryingScapacitySof theSgrassland, since the implementation of the grassland prize subsidy policy.
