| Abstract: | The west area of China including Sichuan, Chongqing, Guizhou, Tibet, Shanxi, Gansu, Qinghai, Ningxia, Xinjiang, Neimenggu and Guilin provide ecosystem deference for upper reaches of Changjiang River and Huanghe River, they are most important bases of agricultural products. Now, fertilizing the degenerated soils is one of the most important tasks for these areas to rebuild the ecosystem. Making full use of composts of stalks, putting organic fertilizers and inorganic fertilizers to rational use, decreasing the pollution of soils by utilization of new agricultural materials extendedly, and improving productivity of soils by combining new techniques properly are the main details of this plan. |
| Keywords: | west area of China soil degradation ecosystem reconstruction degenerated soil fertilization |
