深圳市景观格局空间梯度分异的研究

选择深圳市作为研究对象，利用2006年的遥感影像，研究了深圳市景观空间格局的梯度变化特征。结果表明：景观多样性指数沿梯度区呈先增大后减少的趋势。在城区内其值较低，在城乡结合区域因类型斑块交错分布其值较高；在城区景观斑块密度与边缘密度较小，景观异质性较低。越靠近城乡结合处景观异质程度越大。从景观平均形状指数和景观平均分维数的变化，可看出人为活动的干扰由市中心向郊区发展是呈增强的趋势。以上分析表明景观格局的空间分布与受人为干扰程度有重要的联系。

Analysis of Spatio-gradient Change of Landscape Pattern of Shenzhen City

In this paper,the relationship between the process of a typical rapid urbanization and landscape spatial pattern was studied.The landscape and class-level pattern indices in totsl Shenzhen city were compared.The results showed that the diversity index increased firsdy and decreased lastly according to the pattern grads:the index was bwer in the city center but higher in the connective area of the city and country.Patch Density Index and Edge Density Index were also less in the city center than that of connective area.The closer connective area,the higher heterogeneity it had.Shape index and Fractal dimension also illustrated that human disturbance was becoming stronger from the city to the country.In conclusion.the landscape structure and distribution were highly associated with the human activity.
