Engebei is located on the northern end of Kubuqi desert which is located in the middle reaches of the Yellow River, the northern part of the Ordos Plateau.Being the most serious sandstorm region, Kubuqi desert has a wind erosion index of 4500-15000t per square kilometer every year, an average of 20 to 25 days of sandstorm each year, with a top of 77 to 97 days and a wind speed of 28 m/s.Furthermore, over ten seasonal cannels which originate from the northern ridge of Ordos Plateau run through the desert, flushing silt into the Yellow River when flood comes. Over 31.56 million tons of silt is transferred every year, making it the major sand source of the Yellow river. Therefore, the control and development of Kubuqi desert is of great significance not only to the local economic development, but to the protection of the Yellow River.It is a common problem facing the whole world as how to control desert and make use of desert resources at the same time. The construction of Engebei Botanical Garden fully takes advantage of the good infrastructure and convenient transportation conditions and existing tourism brand, harmoniously blending them with the original park attractions. This will greatly enhance its tourist taste ; promote the rapid development of its tourism industry, followed by the great development of the Desert Control in this region.This sand made botanic garden is divided into three sections from inside out, which is the central area, shelter forest area and sand-fixing technology demonstration area respectively.The central area is further divided into the east and west segments, with the western section making up of 12 differentiated gardens, such as ma-huang garden and caragana garden, and the east being constituted of six special gardens, such as hygrophyte garden and endangered species botanic garden. The shelter forest area circles the central area and is divided into major and affiliated shelter areas.The sand-fixing technology demonstration area is the protected area of the entire botanic garden, it is also the area to demonstrate various sand control methods and high-tech developments, constituted of machinery barrier, biology sand fixing, chemical sand fixing areas.The botanic garden is equipped with water-saving irrigation system, monitoring and lightening system, as well as plan of tourism landscape.The botanic garden is expected to fully display the rich plantation of desert in the temperate zone and successful sand control modes from domestic and abroad, giving the public an opportunity to know about the desert plantations, understand the reason and methods of sand control so as to enhance ecological education, promote exchanges of sand control technology and plantation resources with foreign countries. It is hoped to further develop the research and monitoring of man-made sand control ecological system, so as to provide data support and theory for man-made sand control and plantation resource protection.Engebei Desert Botanical Garden, by introducing international advanced theories and technologies on sand control, and by integrating them with those ideals and methods in landscape designing, expends the connotation of current ecological construction and tourisam.
