Landscape structure is simplicity and homogeneity with the pattern of desert oasis river and canal corridor. The spatial distribution of landscape heterogeneity mosaics is relatively dependent on water resources. In arid regions, the landscape changes rapidly and extensively because of the sensitive landscape ecosystems and fragile regional ecosystems. For the sustainable development of arid regions, the theories and methods for the eco environmental construction and the strategies of ecological construction in the arid regions were proposed in the view of landscape ecology. Keynote subjects of landscape ecology were also discussed. The paper points out that protecting and increasing landscape diversity and heterogeneity are critical to control ecological safety in arid regions.展开更多
文摘Based on the concept of the harmony between human and water and the theory of landscape ecology,the paper has analyzed the concept and connotation of waterfront area.It is considered that waterfront areas have been ecologically sensitive areas under the background of constant advancement of urbanization;and constructing ecological circulation system and reshaping waterfront landscape environment have been top priorities.On this basis,it has studied the classification of landscape ecology and analysis of landscape pattern by taking Nanhudang Lake and the area 500 km within the lake as the research area.In view of different problems of the three landscape sub-zones of Nanhudang,different characteristic eco-landscape constructions have been conducted on each sub-zone according to local conditions,so as to achieve the biological balance of waterfront areas,and efficient and harmonious sustainable development of waterfront landscape.
文摘This paper analyzes the characteristics of the landscape structures and landacape ecological processes in arid regions of China. Landscape structure is simplicity and homogeneity with the pattern of desert oasis river and canal corridor. The spatial distribution of landscape heterogeneity mosaics is relatively dependent on water resources. In arid regions, the landscape changes rapidly and extensively because of the sensitive landscape ecosystems and fragile regional ecosystems. For the sustainable development of arid regions, the theories and methods for the eco environmental construction and the strategies of ecological construction in the arid regions were proposed in the view of landscape ecology. Keynote subjects of landscape ecology were also discussed.
