| Abstract: |
| Jinghe basin is a serious soil loess area of China.This paper analyzed the environment characters of the Jinghe basin with an area of 45.421 km2,which includes fragile ecosystems,water resource shortage,heavy loss of water and erosion of soil,low vegetation coverage,high soil cultivated index and intense population and land pressure.The human activity in the region is accelerating the environment deterioration.Based on the analyses,the strategy for ecological construction and the mode for sustainable agriculture development are put forth in the paper.The strategy includes implementing forest,bush and grass projects to enlarge vegetation overage,constructing high-efficiency rain-collecting and water-saving projects and adjusting agriculture structure to develop agriculture with local specialties and advantages.In addition,the agriculture of the Jinghe basin should adopt the sustainable development mode.Jinghe basin can be classified in four kinds of basic ecological zones,which include the water-soil preservation zone,the mountainside water-soil preservation and economic zone,the basic farmland zone and the upland high-efficiency economical zone.Based on the local conditions in the zones,various countermeasures should be taken to realize the sustainable development in the region. |
