The Study Of The Driving Forces To Land_use Change In The Coastal Zone Of Hebei Province

The study on the driving forces and land use change is the forward problem of the geology, of which the land use is one of the most important component part and central issue in the global change study. The land use change means the land structure and features converting because of the human direct and indirect activity on the earth. The study on the driving factor of the land use change will be helpful to explain its system, and then imitate and forecast the future direction and result of the land use. Because of the special position and environmental features off the coast areas, it is meaningful geographically to the study on the land use/coverage change.This paper takes the coastal area in Hebei province as the study zone, and employs the satellite remote sensing statistics and geographical information system, the global location systematic technology and so on to obtain correctly the situation and features of the five periods of the TM video statistics in 1956, 1970, 1987, 2000 and 2005. In addition, we collect the data of the present situation statistics, soil and social economy in the study area, and discuss quantitatively the effect of the driving factors on the land use change drawing support from the space analytical method of the geographical informational system and the mathematical statistic method. In the end of this paper, it analyzes deeply about the land use change driving in the study zone based on the ClUE-S model.This paper starts with the nature and social economy to study the driving in coastal area of Hebei province. In the natural field, it mainly evaluates and analyses the appropriateness of the land use by the natural potential, and then analyses further the effect of the land appropriateness on the land structure. And in the social economic field, it reveals the driving system of the land use and coverage change in the coastal area in Hebei province with the quantitative method by population and economic driving factors.It not only analyses the driving from the typical land change, but also considers the influential land from the driving factor point of view. It pays emphasis on the various nature, social, economic factors and its driving system, along with the mutual association and synthetic analysis on the driving factors.During the course of the quantitative driving factor analysis, the paper leads into the space and time scale analysis, and the synthetic analysis of the regional and massif scales. The paper mainly introduces the driving analysis of the land use space, and reveals the space driving features since the 50 years horizontally and vertically. The innovation of this paper is as follows:(1) In the Quantity analysis of the driving factors,the text includes the scale analysis of space and time ,also have integrate analysis of area and parcel scale. All around the paper shows the driving mechanism of the land_use change and expounds the principle through many kinds of math_statistics.(2) The paper emphasizes the driving forces analysis of the land_use space distributing,and opens out space driving characters of land_use change on the coastal zones in HeBei province along 50 years from north to south.
