| XinlinGol League in Inner Mongolia belongs to arid and semi-arid temperate climate zone, which is an important ecological barrier in north China. The ecosystem in the region was severely damaged by irrational use of long-term. The relation that between pastoral and people has been changed in the region. Snow disaster, drought disaster and other natural disasters are restricting the health of livestock development of the economic and social in XinlinGol League. Select a reasonable way of escaping and counteracting disasters to reduce economic losses in pastoral areas, to become the region's urgent need to achieve sustainable development. This paper mainly makes snow disaster as the research object, which is one of the most damaging natural disasters in the pastoral area of Inner Mongolia. Select three big snow disasters in 1962, 1977 and 2000, and select the typical four livestock counties as the research area. Through interview method and survey method to obtain basic information of snow disaster, with the mean and correlation analysis, to compare three times'snow disaster in XinlinGol League on the horizontal and vertical, to analyze the causes of livestock losses by snow disaster. This article is divided into five parts:First, the theoretical study of domestic natural disasters and the situation of natural disasters of Inner Mongolia are analyzed, and snow disaster is restricted as the important factor for development of livestock husbandry. In academia, there are two different points of view and mitigation measures.Second, the article discusses the study area of natural, social, economic, ecological profiles, presents the contents, methods and technical route of this study.Third, the first outlining the basic conditions of the three big snow disasters; Second, using correlation analysis and comparative analysis conducted on the three vertical comparison of the snow disasters, summed up the loss of livestock and hazard snow grass height; Third, the use of contrastive research on the three horizontal comparison blizzards, three big snow disasters obtained different research areas and analyze the reasons for the loss of livestock research.Fourth, in a word, through the three large snow disasters on horizontal comparison and vertical comparison, there is a result that the snow disaster in 1962 that the traditional nomadic grassland livestock husbandry in the study area for disaster prevention in the success of reducing livestock losses, while the basic settlement, nomadic narrow the scope of area suffered serious losses; snow livestock losses in 1977, mainly "Big Mess" system error caused by the special decision-making and snow; livestock losses in 2000 mainly due to the snowstorm XinlinGol League, after a long time to settle the whole grassland degradation, reduced productivity, high grass reduced, and the nomad disappeared can not avoid natural disasters. From this, 1962 and 1977 rangeland livestock is mainly due to a serious loss of tolls to reduce the scope and distribution of nomadic"Big Mess" system, rather than on the grassland animal husbandry, " vulnerability"feature. The XinlinGol League in recent decades mainly the loss of livestock grazing, and nomadic settlement disappeared, due to be livestock, livestock often trampled grass and soil trace elements can not hurt to add the swap to pasture decreased productivity, lower grass height, so little snow will cause a big loss. Thus, a pastoral area in Inner Mongolia is settled livestock production has a"vulnerability " feature.Fifth, through the conclusions to table mitigation strategies for snow disaster in Xilinguole League: (1) Restoration of nomadic production, to improve the geo-hazards. (2)To build the system of snow disaster monitoring, forecasting and early warning assessment. (3) The establishment of cooperation between the government and the herders'mitigation system. (4) The nomadic is an effective way of escaping and counteracting disaster. (5) By adjusting herd structure to reduce livestock losses. |
