Résumé partiel
Maintaining reasonable stocking rate is of great significance to maintain the balance of grassland ecosystem in Inner Mongolia.Accurate evaluation of grassland livestock balance to households can provide theoretical basis for grassland grazing management.Herdsman is the basic production unit of grassland utilization and the executor of grassland livestock balance.The policy of balance between forage and livestock regulates the balance between forage supply and livestock forage demand by implementing the ideal state of determining livestock by forage and maintaining livestock carrying capacity.At present,there is a lack of micro scale analysis in the research,which can not fully explain the current situation of household specific grassland livestock carrying,and lack of accuracy evaluation.The final result is that the livestock raising scale of herdsmen is adjusted according to the market and the carrying capacity of experience,and its strong subjectivity leads to the effect of the implementation of the grass livestock balance policy greatly reduced.Inner Mongolia has a long span from east to west.The grassland types include desert grassland,typical grassland and meadow grassland.The poor natural conditions and complex socio-economic conditions,as well as a series of ecological damage and environmental degradation problems caused by unreasonable development and utilization in recent years,such as deforestation and overgrazing,make the ecological environment of Inner Mongolia Pastoral Area more tolerant and resistant to external interference Therefore,it is very important for the sustainable development of the ecosystem to balance the livestock and grass in the family pasture.Therefore,this paper selected typical counties from meadow steppe,typical steppe and Desert Steppe as the study area,using ground vegetation sampling data,NDVI data,meteorological data and herdsman questionnaire data,combined with vegetation sampling method,questionnaire survey method,remote sensing inversion method,quantitative analysis method and qualitative analysis method,evaluated the current situation of grass livestock balance in the study area and analyzed its influencing factors On this basis,the paper provides countermeasures and suggestions to solve the problem that it is difficult for some family ranchers to achieve the balance of grass and livestock in the current price segment.The main conclusions are as follows(1)The average grassland area of Xilinhot City is 472.15hm2,that of chenbalhu banner is 438.86hm2,and that of Damao Banner is 357.35hm2 ;the actual livestock carrying capacity and grass yield per unit of chenbalhu banner are the highest,491.63 sheep unit and 2014.65kg/hm2respectively,followed by Xilinhot City,479.05 sheep unit and 1494.33kg/hm2respectively
