摘要:
在江苏沿海地区沙壤土区种植意杨、银杏、柿子等经济乔、灌木水土保持的基础上，种植菊苣、德宝、爱国草等牧草，结果表明：在汛期可增加地表覆盖度46%～84%，减少土壤侵蚀量49.9%～71.4%，土壤有机质增加19.1%，土壤年脱盐率达26.5%，夏季地表温度下降1.8～4.6℃，减少蒸发0.9～12.6 mm/d，相对湿度提高 14%～20%，增加经济收益4500元/hm2，其水土保持效果、生态效益、经济效益得到明显改善和提高。
Abstract:
In coastal regions of Jiangsu Province,not only tress,such as Italian tree,gingkgo,persimmon,but also grass,such as Juju grass,Derby,Aiguo grass,etc.,were planted to conserve water and soil.The results showed that in rain season,land cover rate increased by 46%～84%,soil erosion decreased by 49.9%～71.4%,soil humus increased by 19.1%,desalination increased to 26.6% per year,tempereature of land surface in summer decreased 1.8～4.6℃,soil evaporation decreased by (0.9)～12.6 mm/d,relative humidity increased by 14%～20%,economic benefits increased by 4 500 yuan/hm2,the effects of water and soil conservation,ecological benefits and economic benefits were greatly improved.
