Allocation about Artificial Arbor Trees According to Site Adaptibility in the Key Areas of Soil and Water Losses of the Loess Plateau

It is a key points to assure the tree survival and afforestation to allocate trees properly according to the different site conditions and adaptability of different trees. The mothod of “comprehensive evaluaiton method” and “anologism of biology and ecology” are used to study the evaluating principle, method of the adaptibility of the artificial arbor trees in the main areas of losses of soil and water of the Loess Plateau for rehabiliation, harnissing the lossses of soil and water, and promoting the evironment construction in the Development of Western China. The results show that two methods are suitable to evaluate the arbor trees in the areas and 46 suitable arbor trees have been gained with the aid of the first method, and 47 suggested arbor trees have been dertermined from the second mothod.
