The Character Of Land Use/Cover Change In Chifeng And The Humanity And Physical Factor Influences Analyse

Since the early stage of the 1990s last century, the land use and land coverage change is concerned by vast science researcher and government department, and become one of the most important aspects of changing research work in the whole world. The research results of this paper can offer the typical case that the land use dynamic change for studying in global change. In addition study Chifeng in developing the course and consequence to the high strength of the land within short-term, study the reinsertion process of its ecological environment, the meaning and reference function that choose to warn in regional development path to correlated with other economic conditions naturally, have typical meaning and representative ness. The research results of this text reflect in several following respects mainly: Having tried to use the small wave to vary and merge and use BP neural network to drawn the use and coverage of land in China by information on the technological method, the overall categorized precision is higher than 80%, kappa coefficient is greater than 0.75. Through it finds Chifeng city land use and coverage and its natural space distribution of key element very identical space distribution pattern to analyze, the main distribution area demarcation line on the meadow, cultivated land, forestland is very obvious. The land of Chifeng utilized the dynamic change to reflect in grain for green mainly in 1995 - 2000, the typical district land in Chifeng utilized the dynamic change to embody in grain for green and the industrial and mining, resident's land used for expansion respect in urban and rural areas mainly in 2000 - 2005. Having analyzed that the natural factor and humane factor utilize space distribution, land to utilize influence of dynamic change space distribution to the land with this stationery body, the conclusion drawn is that a macroscopically policy is that the natural factor utilizes the change to have very strong control function to the land, through analyzing relevantly that finds that besides macroscopically policy in the humane factor, economic development is to urge the land of Chifeng to utilize the main factor changed.
