Abstract: Returning farmland to grassland is conducive to improving the ecological environment and promoting the sustainable development of the rural economy. This study analyzed the relationship between the policy of returning farmland to grassland and household income of farmers and herdsmen of Ledu County,Gangcha County and Jianzha County,Qinghai province. These counties are agricultural income dominates,animal husbandry dominate,agriculture and animal husbandry dominate,respectively. The results showed that: In the overall analysis,compared with farmers and herders who were not involved in the policy of returning farmland to grassland,the policy of returning farmland to grassland reduced the per capita agricultural income of farmers and herdsmen (P<0.05) and increased other income per capita of the families significantly(P<0.05),but had no significant impact on the total income per capita of the families,and the total income per capita of the family were different among counties;The increase in the amount showed a trend of first decrease and then increase,according to the fitted curves,the total per capita income of the households who have returned from farming was lower than that of farmers and herdsmen who have not returned where the subsidy amount is less than 348.98 yuan. Therefore,it might affect the livelihoods of farmers and herders when the subsidy amount is tool low. Therefore,policy standards and measures should be improved and modified according to the local conditions.

摘要： 退耕还草有利于改善生态环境,促进农村经济的持续发展。本研究以青海省以农业收入占主导的乐都县、牧业收入占主导的刚察县和农牧业收入兼有的尖扎县为研究区,从单个农牧民家庭的角度分析退耕还草政策与农牧民家庭收入的关系。结果表明:总体分析时,与未实施退耕还草的农牧户相比,退耕还草政策显著降低了农牧民家庭人均农业收入(P<0.05),增加了农牧民家庭人均其他收入(P<0.05),对家庭人均总收入没有显著影响,且家庭人均总收入在不同地点表现不一致;在已实施退耕还草政策的农牧户,家庭人均总收入随着补助金额的增加而呈现先降低而后增加的趋势;根据拟合曲线分析发现,当补助金额在0～348.98元时退耕户家庭人均总收入低于未退耕农牧户,这说明补助金额过低时不利于于农牧民维持生计。因此,应当因地制宜地制定政策标准和措施。
