%X As a typical city in China's fast urbanization,Shenzhen has been studied on the principle of road network structures and its landscape ecological effects in this paper.The integrated GIS technology,network structure analysis,landscape pattern analysis,and correlation analysis were used in the research.By dividing land of Shenzhen into 24 independent units,the paper discussed the correlations of each road network feature,effects of difference of urbanization level on road network structure features,as well as the landscape pattern effects of road network features at both land scale and class scale.The results indicated that with the increase of the density of urban construction land,the traffic density,the nodes and corridors of road networks increase,while the complexity of road network structure and the landscape pattern indexes decrease.The main restrictive factors are protection requirements of natural resources and eco-environment,which can result in an increase of road network complexity and decreases of development level of road structure network and network pattern indexes.No obvious constraint had been found in Shenzhen on road network features and landscape patterns on land scale.Road network features present two comprehensive effects,i.e.,environmental protection constraint and spatial attraction,on construction land distribution;while environmental protection constraint,spatial resistance and physical segregation are the three effects on woodland.
