| 摘 要： | 根据不同利用类型土地生态效应的异同,对汕头市2003年1∶1万比例尺土地更新调查数据的土地分类系统进行调整,将全部土地景观划分为耕地、林地、园地、草地、居民点及工矿、交通、裸土地和水域等8类.在GIS的支持下,提取各类型土地景观斑块的数目、面积和周长等信息,据此对斑块景观的数量、面积和形状等特征,以及区域景观的多样性、均匀度和优势度,集中性和区际意义等进行分析,从而总结出全市范围及六区一县土地利用空间格局的景观生态学特征.

| Abstract: | Land use and land cover changes have been hot spots in geography and ecology,in which land use spatial pattern is one of the core research objects.By taking Shantou city as an example,the land use spatial pattern is analysed from the view of landscape ecology.According to the different ecological effects of each type of land,the classification systems used in Shantou land renewal investigation in 2003 are adjusted,and the land is divided into 8 types such as plantation, woodland,garden plot,grass plot and so on.Under the support of GIS,the information about the number,area and perimeter of each patch is collected.The number,area and figure characteristics,and diversity,evenness,dominance,centrality and interregional significance of the landscape patches in higher spatial level scale are studied,and the landscape ecological characteristics of the land in Shantou's 6 districts and 1 county are summarized.two main conclusions are given: human disturbance and!spatial heterogeneity of land use.It is considered that different types of land should coexist harmoniously,so as to attain sustainable economic development of Shantou. |
