Effect of grassland inflow on herders'grazing inten-sity—based on the perspective of self-owned grass-land and rent-in grassland
[Objective]The difference of grazing intensity between herdsmen's self-owned grassland and rent-in grassland was studied,so as to correctly understand the real effect of grassland transfer,and to promote the stan-dardization of grassland transfer and the improvement of grassland ecological environment.[Method]Based on the field survey data from six towns(Sumu)in West Ujimqin Banner,Inner Mongolia,the difference of self-owned and rent-in grassland plots on grazing intensity of herdsmen were investigated by propensity scoring matching(PSM)method.On this basis,ordinary least squares(OLS)was used to further analyze the possible role of different contrac-tual arrangements on the grazing intensity of herdsmen in rent-in grassland.[Result]The results show that:1)The grazing intensity of herdsmen on their self-owned grassland and on the rent-in grassland was different.After transferring-in grassland,herdsmen would reduce the grazing intensity of their self-owned grassland and tend to stock more livestock on the rent-in grassland.2)There were differences in the effects of different contractual ar-rangements of the grazing intensity in the rent-in grassland.Signing written contracts and transferring form relatives and acquaintances could restrain the grazing intensity of herdsmen to a certain extent,while agreeing on the length of the transfer did not have a significant effect on the grazing intensity of herdsmen.[Conclusion]In the process of sub-sequent grassland transfer,it is necessary to focus on the supervision of use degree of rent-in grassland,enhance the binding force of the transfer contract and support the new animal husbandry business entities.
