Analysis on the Correlation between Spatial Pattern and Functions of Land Use——A Case Study in Tianshui City
摘要
Abstract
Relationship between the structure and functions of regional land use is the core issue. Based on the data of land use change in Tianshui City, Gansu Province in 2005, the spatial pattern and functions of land use types in the county and district levels of the city were analyzed so as to reveal the land use structure by selecting the centrality index, holistic combination, location index, landscape diversity index, homogeneity index and dominance index of land use. The results show that the combination of land use types in Tianshui City was dominated by farmland-woodland-grassland; centrality index of land use in Qingshui County was the highest (0. 082) ; cultivated land, urban and rural construction land, traffic land and water conservancy land had the location significance; the diversity index of land use in Zhangjiachuan County was the highest (2. 352) , the dominance index of land use in Maiji District was the highest (1.604 ) , and the homogeneity index of land use in Zhangjiachuan County was the highest (0.742). The study results also reveal that there was a positive correlation between the diversity index, homogeneity index and combination of land use types, but a negative one between the dominance index and combination of land use types; there was a positive correlation between the population density and land use degree, but there was no correlation between the economic density, land use degree and location index. The study results can provide the reference for optimizing land use structure in the Loess Plateau in east Gansu Province.关键词
