Research Of Carrying Capacity On Resource And Environment In The Campaigns Of Development Of Northwest China

The campaigns of development of West China are an important measure taken to achieve the third strategic target. As main parts of West China, Northwest China holds on the significant status in the campaigns of development. But now strategy related to development of Northwest China doesn't unify, what brings inconveniences in the practical campaigns of development. Simultaneously, mistake ideas of "vast territory and abundant resources" toward Northwest China induce people to only describe the campaigns of development of West China as exploitation of natural resources and even liability to make reclaimed farmland degenerate, what badly disturbs and imperils sustainable development in Northwest China.Study on carrying capacity is a core content of sustainable development, and it can indirectly reason whether development is sustainable or not by analyzing situations about surplus/overload of carrying capacity on resource and environment. But, at present study on carrying capacity all deals with single resource, especially more on carrying capacity of land resource. As factors are few, study on carrying capacity can't come into being accurate evaluation on overall situations, even result in misconceptions of " to only see the tree but the forest". Consequently, the article analyzes and evaluates carrying capacity on resource and environment in Northwest China with fashionable international method of footprints analysis, and discusses development patterns in order to offering decision-making bases and references for the campaigns of development of West China.The article includes eight chapters. Chapter One is introduction, accounting for objects and significances of study, discussing fundamental situations on population, resource and environment in all aspects at home and abroad, analyzing and summarizing theories of regional exploitation at home and abroad. Chapter Two analyzes gap situations between East China and West China at present, lagged roots in West China, and clarifies important significances on the campaigns of development of West China. Based experiences and lessons on regional exploitation at home and abroad, Chapter Three debates taken measures and advertent problems in campaigns of development of WestChina. Chapter Four ascertains ambits of the Northwest China, analyzes resource and environment situations, and illuminates advantages and disadvantages of resource and environment in Northwest China. Based definition on related concepts to carrying capacity on resource and environment, Chapter Five systemically expounds upon theories of carrying capacity on resource and environment. With analysis of method related to carrying capacity, Chapter Six calculates carrying capacity on resource and environment in Northwest China in 2001 by two ways of ecological footprints and carrying capacity relatives, analyzing and comparing the two results. Chapter Seven analyzes principles and countermeasures for enhancing carrying capacity on resource and environment in Northwest China and discusses problems relating to development of small town in Northwest China. Chapter Eight draws main research conclusions and discusses certain issues.Main fruits and conclusions are as follows:(1) Gap appearance are various between East China and West China and gap will be widened according to current trend; among various factors resulting in gap, mutable factors such as policy, system and manpower etc. are stressed during exploitation in the future; the existing gap has not only positive action but also negative action and we should utilizes its positive aspects to avoid negative affect spreading during exploitation.(2) On the premise of insisting on sustainable development, the campaigns of development of West China going on wheels should take economic increase as core, takes policy, system, and framework as safeguard, takes devotion of manpower capital and construction of fundamental facilities as pull, and takes related industrialization as thrust. At the same time, for changing of environment conditions at home...
