Study On Drainage Pattern And Arrangement Of Vegetation In Greenland Drainage Area In Southeast Asia

With the development of economy and the transformation of "China Belt and Road Initiative" strategy,many enterprises China abroad to expand overseas market.Southeast Asia is the first choice for Chinese companies to invest in overseas markets because of its rapid economic growth and its geographical advantages and similar cultural background.The difference in Southeast Asia and China in development and construction due to climatic conditions and hydrological conditions,building materials market,the quality of workers and other conditions,in accordance with the construction experience of the domestic,in the construction process encountered many problems.This article from the landscape perspective,sediment pollution problem carrying on the construction and the Orlando runoff drainage system on site during construction are studied and discussed.In the landscape design,drainage system design is often the design of the subsidiary,in the design of the overall landscape in the layout of drainage facilities to meet the functional requirements.In the southeast and rainy area,more rely on the drainage facilities of civil engineering,due to runoff carrying sediment pollution,easy to form a drainage bottleneck,and green drainage drainage facilities in civil engineering has many advantages,the purpose of this paper is to hope that through my research on the regional project research observation,combined with previous research results,analyzed and summarized suitable for Southeast Asia in rainy area green drainage pattern and plant configuration mode.The main research results are as follows:(1)When the greening project in Cambodia should take into account the construction time,the best construction time is about half a month after the rainy season,the rainy season or the rainy season before the arrival of greening is easy to cause soil erosion.(2)Green land drainage comprehensive benefits higher than the drainage of civil engineering means,in the Cambodian region should give priority to the use of green drainage system.(3)the trees have a good effect on the rain,the turf on the sediment interception is stronger,and shrubs are more likely to cause runoff to bring sand pollution,but the shrub level is the most easy to make greening effect level,Characteristics,summed up for the Cambodian region of the plant configuration model.
