Sustainable Utilization On The Resources Of Grassland: A System Approach

The resources of grassland are important economic resources which is the base for animal husbandry and people in national areas and half pastureland who rely on the foundation subsisting, what is more , it still possesses the important ecology protection function for the particularly minority nationality as far as the west. The utilization of the grassland is connected with the development of ecology and minority nationality district, but according to the whole nation grassland resources and the change circumstances of its utilization, the serious question still exists. This chiefly shows the reduction of the grassland owing to cultivation and " three spend one evil " and high quality grassland specific proportion descend and careless nature and the grassland productive forces descend.In the western areas, the analysis of range from meaning and total capacity is reduced in 3 provinces of Xinjiang, Gansu and Sichuan, and that if the resources of grassland can be used seems very essential. The grassland distributed area of Gansu Province is not only mostly the areas for nationalities, but also it is traditional animal husbandry production base of Gansu Province. From Gansu Province the ecology footmark in recent years, in order to realize the utilization of ecology resources, Gansu must realize the utilization of fossil fuel, reduce the pollution of the environment, and still will strengthen the utilization of the resources of grassland.On the base of the development theory at home and abroad, we can go on researching the ecology environment and natural resources under the development though as well as present time internally, we still can go on to research the foundation which is used to the resources on grassland, we think that the resources on grassland are important pastureland economy resources and the ecology resources, and we hold together that: the use of grassland ecology; secondly, the grassland economy output. Thirdly, the whole pastureland society economy will not be used up in the near future. These three kinds can go on mutually for the condition and serve as the support mutually. Based on this knowledge, under the development theory concept frame, we combine the knowledge of ecology economics and the economic pressure that course the pastureland society economy development requirement wandering about the resources utilization energy on grassland with the economic performance to wander about the resources on grassland forms which is regarded to study the thread, and the pastureland society ecology economy system according to influences the method to resources utilization capacity on grassland and influences content is difference constructed to build into the ecosystem on grassland again and the animal husbandry production system and the rural area society economy system.In fact the utilization in view of the resources on grassland involved is a region or is said to specially designated or appointed going on of society ecology economy system. We select Gansu Province's national pastureland county as the authentic proof research object, and it possesses fixed typicalness and representativeness in the pastureland in the west, and the study is according to the county land within certain boundaries, it is all comparatively moderate to study scope and data, and the material can possess systematic nature and being mutually related with nature.We construct building two ecology economic models of mutual contact high on grassland uses from low arriving and from direct to indirect influences knowledge before authentic proof research, and the change factor with resources utilization capacity on grassland is the thread, and imitating the scope in county land within certain boundaries to influence the grassland resources factors of utilization capacity and influences the course, authentic proof research provides and studies theory frame for us. And we wish that the Zang nationality autonomous county eliminates the northern Mongolian nationality autonomous county to accomplish following three parts and commonplace to southern Zang nationality autonomous prefecture to Gansu Province, Ma's song and 3 county and west of a river districts in the river and the respectful Nan Yugu clan autonomous county and the authentic proof analysis of A Kesaihasake autonomous county.First, we find each the nation pastureland county owing to the geographical position, natural environment together with resources the difference of gift ability by way of using many quotas to the ecosystem on Gansu Province nation pastureland county grassland, the ecology can be used for longer time so that the development ability exists bigger difference and fairly more protruding can be utilized, and the county in each pastureland only takes measures suited to local conditions, essentialism system, policy system, grassland management system, technology system and that the government compensates the system each other that can solve the good grassland ecosystem.Second, Gansu Province national pastureland county is wished and can there be some surplus grains in the summer river and the crops root of balloon flower to mend to raise being basically animal husbandry all giving first place to bys herding, this kind of animal husbandry chiefly is the production system of the natural grassland resources source elementary poultry products of production serving as the major forage grass in order to use. We will reasonably dispose year poultry capacity exactly, and builds reasonable the herding utilization system on the utilization grassland reasonably. In view of this, we move that the trend makes static state and analyses and analyses with the trends at present time year poultry capacity ( analysis of section) as well as over the years the year poultry quantitative change to 7 nation pastureland counties in Gansu Province. The summary has been in progress to the major question that exists in Gansu Province nation pastureland county animal husbandry production system, and concluded the measure of optimization animal husbandry in accordance with the question. Combine teacher Min Wenyi and let to the A Kesai county surveying and study that the circumstances and Gansu Province that accomplishes educates scientific research item " animal husbandry modernize of northwest China minority nationality district grasslands and can the go on development research " subject research on the spot, and pointing out that the townization is the important effect that optimizes Gansu Province nation pastureland county animal husbandry production system.Third, we construct model, and it is unpractical that the county in nation pastureland relies on merely the synchronization of grassland resources ( particularly elementary industry of grassland animal husbandry ) realization grassland resources economic performance and ecology beneficial results to increase. Thirth-six qualitative analyses that society economy was developed the quota by way of to Gansu Province nation pastureland county rural area that can get added up the quantitative analysis with many units, not only to the Gansu Province nation pastureland county rural area society standard going on of economy which had been clear and definite knowledge, and still confirmed that rural area society that the builds economy that we construct to influence the reliability of model to the resources utilizations on grassland further. Cases research by way of whole authentic proof research as well as to the A Kesai county showed clearly to promote that each nation pastureland county rural area society economy can develop and the way to relieve resources pressure on grassland.We think to go on research which is used to the resources on grassland at the civilian end, can combine the resources utilizations on grassland influencing the model and lays down the quota the system that the resources on grassland used further to authentic proof researches of Gansu Province nation pastureland county, and can go on the quota system which is made corresponding utilization the measure system, and the hope is carried on authentic proof research to each nation pastureland county once more, and tests quota system and the measure research system. We should adopt to go on to develop in " pressure - state - answers " frame model and the general systematic learning research which studied " the law is introspected in the practice ", therefore the research can constantly be revised and made perfect in wholly studying the course.
