| Abstract: | It is one of the important fields of studies on land science that land type structural and ecological design are being researched.In especial,the vulnerability of mountainous eco_environment and severity of the factitious question is very extrusive.Therefore,it has an important theorctical significance and practice value that the ecological design in the mountainous region are to do on the basis of systematically analyzing land type structure,function and its spatial patterns with the landscape ecology theory and sustainable development norms as the guide.In this paper,on the basis of analyzing the spatial,quantitative and qualitative structure of land type taking Qinling north slope of Shaanxi Province as an example,the ecological design model of mountainous system in study area has been systematically studied.The conclusions are as follows:1.The structural patterns of land type,whose essences are the vertical delamination of land ecosystem,have obvious hierarchic characteristics with the changes of altitude.2.Structural patterns of land type are regarded as the relation both contrast of quality and quantity and spatial composition of land type in appointed area.Analyzing the structural pattern can be beneficial to reveal the heterogeneity and order laws of structure and function of ladn type,and provid academic foundation for land ecology design.3.Vertical natural zone and environmental frangibility in mountainous region decide on the necessity and feasibility of ecological design based on land type patterns.The essence of present use and the suitability of land type and the scientific making measure of mountain ecological design,which can be expressed by models.4.The model of ecological design is one of the forms of ecological design in mountainous region,which possesses ecological sustainability,economic locality and system integrality.Therefore,that the models of and the other special plan.Besides,it is necessary to consider synthetically artificial factors such as input of fund and technique,and change of traditional idea of and use. |
