Guizhou is not only one of province with the most sharp contradictory between population and land in china, but also is a typical acceptability and conspicuous undeveloped region. Because people develop and use land in plunder way, land resources degenerate seriously, ecological environment are getting worse, and heavily threaten sustainable utilization for land resources. Guizhou province covers the water shed of the upper reaches of Changjiang and Zhujiang rivers, serious soil and water losses heavily harm the sustainable development for the watershed of the lower reaches. Sustainable use for land resources is very important to sustainable development of the water shed in lower reaches of the two rivers of Guizhou province. The general consideration for this study is to summarize and conclude existing studied results, to explore the basic category for land resources of sustainable use, establish a theoretical foundation for proving study and policy undergoing. Directed by the theoretical system, a survey was made on the natural, social and economic conditions of the land resources, to reveal the existing problems from natural economic and social aspects. On the bases of the study to provide strategic idea and practical countermeasures and suggestion and Institution design for sustainable use land resources in Guizhou province, the main results are as below. 1. Defined the basic category for land resources sustainable use, provide satisfactorily theoretic guidance for practice of sustainable land use.based on making summarize and conclusion on the definition now inner and outside sustainable use for land resources, the writer recognizes the basic intension for sustainable land use is, first of all, on the basis of to keep and continuously raise capacity of land recourse and ecological environment, based upon the principle that development and use have to combined with protection and management, to use land in reasonable, full, high effective and intensive way. When meet the need for people live to realize of increasing land productivity, improving ecological environment, increasing land capital accumulation. The substance is to bring the effective of land use into harmony with fair in period and space. To realize land sustainable use must follow with five principles, that is, productivity, protection, safety, economy and acceptability. The characteristics in dynamicstate, region, space size, entirety for land resources sustainable use is a theoretical base for choosing and adjusting the concern policy.2. Existing problems and consequences in land use include in Guizhou province ?Stop farm land area decreasing in difficulty, shortage of reserve land. In Guizhou province, with farmland area decreasing year by year, population increasing in high speed, per capital farm land area has been decreased year by year. The percentages of decreased farmland, caused by returned the developed land back into ecologic environment, agricultural structure adjustment, destroy by disaster, construction in out-off farm use, account to 27.6%, 38.3%, 23.7% and 10.4% of the total decreased area of farmland. The area of farmland will be decreasing continuously, following with the urbanization, adjustment in agricultural structure, farmland ecological recovery; This province is not only shortage of reserve farmland resources, with broken distribute and with difficult in development and use, it is easy to cause soil and water losses, to pay great cost as ecological environment. The large basic population courses that the speed of population increasing is hard to drop down rapidly in short time. Therefore, the contradictory between population and farmland will be kept for a long period.(2) Unreasonable constitution for land use. Compared with its characteristics in land resources with more mountains and steep sloop farmland, the land in Guizhou province is over farming, a broad land in appropriate for developing as plantation, forestry or pastureland is not used in full. The level of land for construction is lower, most o...
