Genuine Knowledge and Conclusion Based on the Practice of Urban and Rural Ecological Corridor——The Design of Ecological and Green Corridors in Shanhaiguan District

Abstract

The ecological is derived from the foreign advanced concepts of developed countries, which protects the urban and rural mechanism and context, intensively utilizes land resources and conforms to the requirements of the construction of ecological urban and rural development. The design of Shanhaiguan District Cherry Vale greenway is based on the resources of local mountain, water, springs, and sea, using the greenway design means to design travel, relaxation, culture and other node elements, in which gathers many scattered resources along the and preponderant landscape as dominant resources, not only protect the ecosystem of the natural environment, but also promote the urban and rural harmonious development of social economy. Keywords-local resources; ecological corridor; the way of ecological design; urban and rural industry ecosystem I. BACKGROUND OF THE RESEARCH ON THE URBAN AND RURAL ECOLOGICAL CORRIDORS Corridor is a concept in landscape ecology, it is different from linear or zonal landscape elements on both sides of the matrix, including roads, rivers, belts, tree-lined belt are corridors in the urban and rural areas [1]. The definition of ecological meaning protecting the species diversity, filtering pollutants, preventing soil erosion, windbreak and sand-fixation, controlling flood, etc, which provides the function of ecological service. Ecological is mainly composed of vegetation, water, landscape elements, and it’s the same as green corridor in concept. Rural and urban ecological is the integration of space resources, which uses ecological health to the organic connection. Improving the rural and urban land ecological benefit [2], economic benefit and social benefit, is one of the important choice of promoting scientific development. In today's rapid development of urban and rural integration, urban and rural problems are highlighted, for example: we have a fast progress of urbanization, and at the same time, urban rapid development do not give priority to respect the local ecological environment, which caused destruction of ecology of urban and rural habitats[3]. In this paper, the ecological corridors are the maintenance of urban and rural ecological bridge, to protect the mechanism of urban and rural areas and are also protect arable land, intensively utilize the land resources. II. SIGNIFICANCE OF THE ECOLOGICAL CORRIDOR Ecological has many important functions: controlling the local regional environment, preventing pollution and soil erosion and renovating the function of ecosystem diversity [4]. Building a complete urban and rural road system, promoting the logistics links, prompting the country to support the city and urban to promote the countryside, and the economy, industry and culture to support each other. To make the urban and rural area become regional, scaled, systematic network industry pattern. It’s important for mining local natural resources, improving the industry chain, enhancing the quality of tourism, business services, and it’s the key link to form the urban and rural ecological circulation industry’s chain. III. EXPLORATION AND ANALYSIS OF THE ECOLOGICAL CORRIDOR CONSTRUCTION IN SHANHAIGUAN DISTRICT A. The present ecological and environmental situations in Shanhaiguan District under the urban-rural
