Green sand-grass industry: Dongda group made full use of the historical chance of western development program with the ecological construction as a cutting point and determined to develop green sand-grass industry as the main target for the second pioneering work; And always followed the principle “green color, not the end of ecological construction” and did some practical works. For example: green sandy land and richen people in the sandy region. Therefore, they conducted the project of box-wall paper with pulp-wood made of sand-willow with the annual capacity of 0.5 million tons. There are some other projects matched with it such as planting of sand-willow for 3 million Mu (1Mu≈667M²) in Kubuqi sands, breeding base of 0.2 million meat cows and 0.25 million goats bred in sheepfold. The realization of the above –mentioned projects reflected collectively concepts “three, five and four ones”. Three means that to recover the ecosystem, develop the production and increase the people’s life standard in sand region; Five means that to add green color of sands, increase value of the sand-willow, increase the income of people, increase the efficiency of enterprises and increase the tax of local departments; Four ones means that to bring along a large amount of industries, flourish a number of economies and richen people in the region just in consequence of setting up one project. Finally, “Three high and one low” was realized .They are about to embody higher additional value, higher output and lower cost by use of advanced technology. These projects have got a very high evaluation and confirmation from the famous scientist and academician Mr. Qian Xuesheng in our country. He wrote, “I think Dongda group is undertaking a great cause------not only combine the three parts of forests, grasses and sands in one and to create a big agriculture in 21st century in the sands region in the northwest part, but also realize the industry chain of agricultural, industry and trade in one so as to reach a good circulation for greening the sands, increasing the income of people and increasing efficiency of enterprises.” Besides, these projects brought a happy life for 5 counties, more than 40 towns and villages and 0.5 million peasants and herdsman in this region. In 2005, the group actively responded to nation’s call to help the peasants and herdsmen lead a happy life. At the same time they conformed to the Nation’s reform policy “Return forest from cultivated land and return grass from cultivated land” and actively took part in the task of government -----“Help the Poor”. They offered RMB 1 billions yuan to build up a new village at Yandian town in Erdos city and relocated the peasants and herdsmen in adverse ecological circumstance to the new village with the policy “migrating without land and help the poor through industry”. They built up a new town for 30-40 thousands people in the land of 8 square kilometers.They solved the water problem in the new village by using some special methods. And they helped the peasants and herdsmen with the reasonable measures. It was that men went in for multi-works, such as planting sand-willow, breeding and so on; Women did some businesses to realize the circulation of economy and recover the destroyed ecological environment in order to achieve the harmony of human being and nature.
