Wetland as one of the natural landscapes with the richest biodiversity and most closely related to our life is widely distributed all around the world, and capable of storing fl ood, preventing drought, purifying environment, adjusting climate, controlling pollution, maintaining regional ecological balance. Nanchang is famous for "City in the Lake and Lake in the City", and this paper begins with wetland resources in Nanchang City, analyzes problems of local wetlands. Taking the design of the Aixi Lake Wetland Park for example, this paper proposes suggestions for the renovation and improvement by analyzing the problems of its current landscape pattern, and specifi c problems in the landscape design of wetland park, and summarizes the ecological model fi t for the landscape design of urban wetland park in Nanchang City. The research contributes to the ecological restoration and conservation of wetland resources in Nanchang.  相似文献

This study focused on riparian vegetation buffer zones on the basis of low influence development(LID) and landscape restoration. Three types of land were selected to conduct comparative study. The types are buffers in urban districts,buffers in rural areas,and buffers in natural regions. These types basically reflect major ecological issues in different landuses. The follow conclusions were drawn:(1) there are different ecological issues in these 3 types,making the functions of buffers different.(2) The 3 types demand different ecological issues to be solved: Type A,functionally-diverse riparian landscape should be planned to enrich recreational activities and improve river's condition. Type B,agricultural areasource pollution needs to be cut down to sustain the stability of water conservation and ecological system. Type C,eco-conservation and various habitats for creatures are required.(3) Different planning methods were used respectively in the 3 types,construction methods were proposed for each type correspondingly and expressed in graphical ways in expectation of being instructive to the construction of eco-riparian landscape.  相似文献

Sustainable management of scenic and recreational forest based on the integration of forest landscape beauty and recreational functions is the foundation of forest tourism. Adhering to the principles of structural optimization, healthy and vital, beautiful landscape, sound function, and comprehensive benefi t, the hotspot and core task in the current construction of scenic and recreational forest is to conserve, transform and improve forest landscape. The ThousandIsland Lake National Forest Park is endowed with peculiar island scenery, it is necessary to construct a stable threedimensional comprehensive protection system covering "mountain, land and lake", enhance the ecological environment conservation of the lake as well as the lakefront wetland, promote the ecological restoration and coloring construction of forest, protect integrality and diversity of the biosystem, and construct ecological urban-rural system using regional scenic spot concept, so as to build the lake into a model of the sustainable operation of scenic and recreational forest.  相似文献

太宽河自然保护区栓皮栎种群动态研究   总被引:1,自引:1,他引:0  
栓皮栎是太宽河自然保护区主要植被建群种之一,研究其种群动态对该保护区生物多样性保护和恢复以及维持生态系统平衡都具有重要意义。通过径级结构分析和树高与直径的生长关系分析,表明该种群为增长种群,树木年龄不超过40年,处于幼龄向中龄发展阶段。静态生命表分析较好地反映出栓皮栎种群生长历史中的消长过程,清楚地透视出20年前坑木择伐对种群动态的长期影响,即径级V和VI(直径8~12 cm)存活株数异常增加、存活率提高、死亡数和死亡率出现负值以及平均期望寿命降低;而相应地对径级III 和IV带来与径级V 和VI相反的作用。该种群的存活曲线符合Deevey II 型; 死亡曲线波动异常,反映出强烈的人为干扰影响。建议减少人为干扰,以保护和恢复该区栓皮栎种群。  相似文献

Ecological planning plays an important role in the construction of cities. Huaibei is a typical coal resource-based city, the abundant coal resources lay a solid foundation for its economic development. Coal mining has induced a series of social problems, and affected the regional social and economic development. Ecological planning of Huaibei City concentrates on ecological restoration of coal mining subsidence, and applies circular economy to develop eco-agriculture, eco-tourism and eco-industry, which will contribute considerably to the economic transformation of the city. Analytic Hierarchy Process and mathematical statistical model were applied to calculate sustainable development indexes of Huaibei from 2002 to 2010. By evaluating the indexes, it was found that Huaibei City has a low sustainable development level, and 3 imbalanced subsystems as the major obstacle. The authors proposed countermeasures according to specific conditions of the city.  相似文献
