Saving “Soil Water Reservoir” is a Key Issue for Integrated Control of Ecological Environment and Sustainable Development on Loess Plateau—— The fourth discussion on “28 words” strategy for land and environment harness on Loess Plateau

The great attention has been paid on the key issues and the counter measures on Yellow River. The fact is that such environment problems are caused by irrational use of natural environment resulting in “three vicious cycle ”. “Vast broadcast with poor harvest; the poorer har vest, the more cultivation ” , this is the chief criminal that causes a vulnerable environment and a long term poverty. Unfortunately, this fact are neglected commonly. Only the raising riverbed and sediment dam and longer period of no water in the river have attracted the attention of the people. Apparently all these vicious cycle is the result of man made geological course, which is adverse to the natural law of Loess Plateau. Its a pity that no profound understand has been got, let alone a effective counter measure.Nowadays the economic development keystone of country is transferring to the middle and west part of China. With the restoration of graceful landscape of the northwest, the sustainable development and control management will become even more important. Therefore all kinds of counter measurements should encounter the change and adjustment of idea and scientific analysis and choice.During the study of the earth ecology and its evolutive process in geologic history the writer find that the occurrence and development of “soil water reservoir” and its evolution are the key and power of the occurrence and development of the earth ecology. Eco environment will been well protected through normal development of “soil water reservoir”. Own to the exclusive dust falling and accumulating environment and continual course of soil formation, the precipitation can infiltrate the “soil water reservoir” directly. All the precipitation can be intercepted and stored successfully in the existence of high infiltration capacity of “soil water reservoir”.As a result, “28 words” strategy for land and environment harness on Loess Plateau should be a good idea in successful control of flood, improvement of socio ecology and sustainable eco environmental development.
