湖北省土地利用格局影响因素研究

Study on influence factors of land use patterns in Hubei Province

将湖北省2009年土地利用图与DEM、气象、水文数据、社会经济数据等数据结合,采用地理信息系统空间及景观生态分析方法,在揭示湖北省土地利用格局基础上分析影响湖北省土地利用格局的主要因素.结果表明:耕地的斑块数量与高程关联最高,再依次为坡向、GDP、坡度、人口密度、降水、气温、路网密度、距水源距离,皆为显著相关.与林地斑块数量关联强弱顺序是坡度、高程、人口密度、GDP、纬度、坡向、经度、气温、降水、路网密度、距河距离.与水域斑块数量关联强弱顺序是路网密度、坡度、高程、GDP、纬度、降水、人口密度、经度、坡向、气温.与建设用地斑块数量关联强弱顺序为气温、路网密度、高程、距河距离、坡度、纬度、经度、GDP、人口密度、坡向、降水.

The characters of land use patterns in Huber Province were revealed using spatial and landscape ecology analysis of geographic information systems. The land use map of Hubei Province in 2009 was combined with DEM, meteorological, hydrological and socio--economic data. Based on this, the main factors influencing the land use patterns were analyzed. The results show that the main influence factors varied with the type of land. For farmland, the most relevant factor with the plaque numbers is eleva- tion, followed sequentially by GDP, slope, population density, precipitation, tempera- ture, road network density, distance to water, which are all significantly correlated. For woodland, the significance of different factors correlated with the plaque numbers are ranked in descending order as elevation, population density, GDP, latitude, aspect, longitude, temperature, precipitation, road density, and the distance from the river. With respect to the water area, the order changed into： road network density, slope, el evation, GDP, latitude, rainfall, population density, latitude, slope and temperature. Besides, the descending order for construction land presents as temperatures, road density, elevation, distance from the river, slope, latitude, longitude, GDP, population density, slope and rainfall.
