The Research On Arid Areas Gully Landscape Eco-design Base On Soil And Water Conservation

Arid Zone gully land ecological environment in China has been is the worst, he lives of the people level's poorest regions. The drought natural conditions and serious soil and water loss is restricting the area development important reasons. It not only destroyed the area of landscape ecology, and limit the development of the local economy, and caused great environmental damage to the downstream. Since the founding of New China, China's leaders at all levels attach great importance to the governance of the gully in arid district, in the hard work of scientists, the support of the CPC Central Committee, National People's concerted efforts and achieved fruitful results, and engineering measures of soil and water conservation and landscape eco-design in theory, was promoted to improve the ecology of the region an important research topic.(1) By introducing the theoretical basis of ecological landscape design and soil and water conservation and research prospects, starting from the soil and water conservation research perspective, the use of preservation of soil and water conservation, water culvert to maintain and improve soil carbon sequestration oxygen, purify the air, wind fixing, maintaining the landscape and ecological diversity, combined with the related concept of landscape ecology, ecological design, and integrated into the landscape of the arid gully to the eco-design theory. Analysis of a variety of different types of gully, the combination of the gully different topographical features and the ecological status, as well as the soil erosion, and summarize different for different regions of the different types of gully and gully landscape eco-design program, and summarizes the characteristics of the design and implementation of conditions, a comprehensive study includes both the soil and water conservation, but also with the landscape of arid gully to the ecological requirements of the landscape ecological design programs.(2) Soil and water conservation, ecology, landscape ecology design, the ecology of the arid areas of gully to control access to large amounts of data, extensive reading literature to understand the latest developments and research advances in related fields at home and abroad. Comparative analysis, compared with typical areas of landscape design with the traditional program, combined with the Henan good ecological agriculture, forestry park landscape eco-design case, the arid gully to landscape ecological design and landscape eco-design specific measures.(3) The Henan JIADUO ecological agriculture, forestry park gully systematic analysis through the establishment of the gully to the plateau edge protection forest landscape, building eco-gully slope landscape, to promote the valley fencing governance, development of valley ecological forest landscape, creating the landscape of the valley ecological wetland and construction of a silt dam landscape construction ecological farmland landscape, improve the landscape ecology of the reservoir, and analyze a variety of soil and water conservation engineering measures and the organizational, economic, policy and other non-engineering measures, and gain as the core of soil and water conservation in arid gully to landscape eco-design research programs throughout the arid gully to the ecological landscape design has a very important practical significance, will be the future direction of development of eco-design of the gully to the landscape of arid areas.Arid gully to the landscape eco-design is a complex systematic project, need to use a variety of subject knowledge, the organic combination of various measures to achieve the best effect in order to ultimately improve the gully to the ecological environment in arid areas. Theories and methods of soil and water conservation will achieve arid gully to landscape ecological environment improvement research direction, this will be a far-reaching process, you need a large number of interdisciplinary researchers to efforts to analyze a relatively large number of engineering case strength, a summary of the kinds of landscape eco-design measures and research methods, as well as the adaptation of quantitative study of the relevant parameters of the soil and gully erosion in model, sediment content, and other relevant data and find out a precise set of ecological landscape design mode, which a radical improvement in the gully to the ecological environment in arid areas, gully to create a good visual effects and ecological benefits of great significance.
