Ecological Coupling Theory and the Method System of Urban countryside Space Planning

Since P. R. China has experienced extensive land resource use, environmental degradation, lagging rural development and other difficulties in 20th century, urban countryside integration and ecological planning has become an important subject to build a harmonious society in the 21st century. The country attempted to use complexity science and ecological thinking based on recognizing the relationship between the city and countryside and raising the city countryside space ecology coupling concept to construct a city countryside space planning methods system consisting of the identification of urban and rural land uses, urban and rural non construction land planning, city countryside coupled environmental conditions assessment, coordinated city countryside space development and city countryside space system fractal optimization, and more.     

Ecological Planning and Design of Urban Green Space System of Sanya City

The construction of International Tourism Island has accelerated the development of Sanya City. The population aggregation and the external extension of urban area have brought a lot of negative effects, such as discontinuities of green space matrix, dysfunction of green wedge permeation, deficiency of eco-corridor, structural imbalance of green space system and so on. The overall layout of Green space system known as One Belt Three Bays, One Core Six Towns, Two Axes Three Wedges, Two Net Synchronous-construction strengthens the eco-connection among different groups and green space in central area of the city, and realizes the collaborative construction of both resource corridor and landscape corridor. The eco-layout of green core, green corridor and green patch helps keep the integrity of large vegetation patches, enhances the eco-connection of different types of green space and improves finger-shaped network of urban green space. The most efficient way to promote the circulation of urban ecosystem and the positive development of Sanya City is to plan multilevel and three-dimensional eco-space structure and maximize ecological benefits of green space system.

Types of Ecological Revetments in Hydraulic Engineering

Compared with traditional bank protection, ecological revetments, as a new type of bank protection, can ensure the sustainable and healthy development of river ecology and has broad application prospects. In this paper, the design principles for ecological revetments and the factors that need to be considered in the selection of revetment plants were summarized; and the types of ecological revetments commonly used in water conservancy projects were summarized and classified according to the proportion of natural materials in revetment materials through domestic and foreign research and engineering examples, and their applicable scope and relevant merits were introduced. In conclusion, ecological revetments should get rid of its own limitations in the practical application process, and the river regulation scheme and revetment type should be selected comprehensively and flexibly combined with the status quo.

Ecological Construction of Urban Green Landscape in Chongqing City

The urban green landscape in Chongqing was analyzed from the view of landscape ecology. It was believed that the urban green landscape was developed rapidly in recent years, but there are still some problems existed, including mainly: (1) the structure of green landscape was unreasonable, (2) the quality of green patches was low, and (3) the function of green corridors was incomplete. It is pointed out that in some urban regions there were lack of green patches, furthermore, some patches were isolated from each other due to lack of green corridors. In the last, taking account of the foundational theory about patch and corridor, some aspects for the design of urban green landscape in Chongqing were proposed: connecting the river and road green corridors and increasing the green patches at the ecological strategic points.
