The Difference Of Herdsman Endowments And Its Social-Economic-Ecological Analysis In Typical Steppe

Grassland as one of the main terrestrial ecosystems has great importance to ecosystem functions and services.Intensified in recent years as global climate change and human activities,90%of the available natural grassland degraded in varying degrees of degradation, and faced with an annual rate of2million hm2incremental grim reality.Herdsman as the microcosmic subjects of production and consumption in grassland is basic decision making unit in pastoral economy and animal husbandry.The ecological problems in grassland under a certain geographical, climatic and other natural conditions,social and economic avtivities,are the result of countless microcosmic subjects game.This study analyzed the field survey and herdsman statistics,setting different herdsman natural resource endowments as a starting point,basing on its cluster,we discuss the relationships of natural endowments on different social, economic and ecological status.1.Natural endowments have significant differences,2741herdsman in XILINHOT can be clustered and analysised based on natural endowments such as pasture area, average elevation, average slope, annual average precipitation, annual average temperature,2000-2012maximum biomass per unit area,2000-2012minimum biomass per unit area and2000-2012average biomass per unit area to explore its attributes and differentiation characteristics. The results showed that:(1) the study area herdsman’s natural endowments have significant differences,2741herdsman can be classified into nine groups, annual average precipitation and average elevation make contribution to the classification, pasture area also play decisive role.(2) Restricted by natural endowments, the grass yield per unit area, total yield and its fluctuations in different years of herdsman are respectively different.2.This reserch found that natural endowments are related to social and economic factors by analysising herdsmans’ natural endowments and socio-economic factors. Annual precipitation and the population of livestock are positively correlated, average slope and the investment of purchase fodder are negatively correlated, when other endowments factors have little difference.3.Different group have different natural endowments,but their vegatation trendency shows amazingly consistent. Since1983, the grassland shows continuingly degradation,in1989and2000the degradation become more serious, the trendency slowed down in2011. The second group shows diffenent status,its degradation strats from2011.
