[Method] The dynamic changes of pollutant concentration, precipitation and flow during the rainstorm on August 12, 2010 were monitored at the outlet of Menglianggu watershed. [ Result] During the rainstorm, the generation of runoff was sudden and ephemeral, and the peak of the runoff lagged behind that of rainfall intensity; the concentration of AN and TN increased firstly and then tended to be stable, while NN concentration had no significance change at the beginning of the rainfall, then improved gradually and tended to be stable fi- nally; DOP concentration had no obvious change during the rainstorm, but the concentration of DIP, DP, PP and TP rose firstly and then tended to be stable, and the peak values appeared before the peak of the flow. In addition, the output concentration of TN and TP was far higher than the standard concentration of water eutrophication. [ Conclusion] The study can provide scientific references for the reasonable control of non-point source pollution pollution in Yimeng mountainous area.展开更多

The status quo of the agricultural and the internal structure of agriculture in Yimeng Mountainous area are analyzed through the method of comprehensive appraisal of the improved factors. The safety coefficient of the comprehensive appraisal is from 2.626 696 to 4.987 546,which is exclude in the safety extent, so it needs adjusting. At the same time, the internal relations of the internal structure of agriculture in Yimeng Mountainous area are studied by using the relativity analysis. The overall agricultural structure of Yimeng Mountainous area is in negative correlation to planting structure and forestry structure, and in positive correlation to livestock breeding industry; the plating structure is in negative correlation to livestock breeding structure and in positive correlation to forestry structure and the forestry structure is in negative correlation to livestock breeding structure.展开更多
