- W2353507774 abstract "Ecological economic principles were applied to study the economic and ecological effects of the newly introduced and built pear tree-upland rice system on sloping land in Three Gorges reservoir area in this paper.Compared with the pear mono-cropping system,the experiment result from the newly designed pear tree-upland rice system indicated that:(1)This system improved soil fertility,reduced soil and water losses and decreased the soil erosion.(2) Weed and pest can be significantly controlled in the system so that the application of herbicide and pesticide can be reduced,resulting in 60.19 kg N /hm2 and 8.0 kg P/hm2 of non-point source pollution load decrease.(3)It could notably utilize local natural resources with the land utilization efficiency increasing by 44%and the energy economic index enhancing by 2%.The results showed that pear tree-upland rice system is a high-efficient intercropping system with good ecological and economic benefits for farmers and has a prosperity in Three Gorges reservoir area of China." @default.
