Urban Landscape And Aquatic Ecosystem Protection Research

Based on degraded water ecological restoration techniques, the specific measures and methods, mainly physical, chemical, biological / ecological technology, these methods for different landscape water ecological restoration provides a theoretical basis. Especially biological / ecological and Technology Act is the urban landscape water for the ecological restoration of water important theoretical basis, water is ecologically sustainable development of important ways. The method, the more natural river-building technology is the city Waterscape building commonly used method. Characterized by the river ecosystem restoration, restoration of the river to enhance the self-purification capacity. More natural river-building technologies, including biological and physical two parts. More natural river-Construction Technology Application of biological mainly aquatic animals and aquatic plants. The use of aquatic plants purify the river water is mainly absorption of nitrogen, phosphorus and nitrogen they absorb water. P ability is also very different, and some aquatic plants can be higher concentration of heavy metal ion concentration; Some were able to inhibit the growth of algae. In addition, the plant could reduce the water flow rate through the promotion of the settlement of particles.The article Nanjing Qinhuai River environmental restoration project on biological / ecological theory of technology research and application. In practical application focus on the biological and physical structure of Nanjing Qinhuai River environmental restoration of biological building program. According to the rivers of different spatial scales. Ecological Protection of the overall program, including construction of river communities vertical channel programs and vertical Community Building program. Vertical Construction of the river communities program includes the reconstruction of the river often refer to the following regional level. Regional changes in the water level above flood level and the region (that is, with aquatic, wetland and terrestrial Strip belt) and the plant community. Different view of the regional scope of the elevation, the regional plant selection and configuration program, Qinhuai River so that river forming vertical belt including aquatic, wetland and terrestrial Strip with the integrity, health, stability, and with a certain self-adjustment ability of ecosystems. Construction of the river vertical communities Qinhuai River program is based on environmental characteristics, functions and landscape requirements study the Qinhuai River landscape character of the five, Sancha Riverside style of stone cities of the historical outlook, West Water Park features of the relations, the Chinese character of the castle door, baby ecological character of the river. Construction of the river communities of vertical integration of the Qinhuai River Landscape features and sections of the actual situation, Reach raised with the suit the plant community reconstruction programs.Greenbelt system in conjunction with urban building the landscape water when fully consider the ecological benefits of water, establish urban landscape water eco-efficiency indicators system, will be urban landscape water-building, research, provide the basis for restoration. Based on the research results, the urban landscape water ecological evaluation of the three indicators system. According to the index system, the improvement of the environment after the Qinhuai River in Nanjing for the ecological evaluation, the results of good, stated Qinhuai River in the improvement of the environment after the hydrodynamic conditions, water environment and water landscape received a lot of improvements.
