6) nutrient losses
养分流失
1.
Based on the observation in runoff plots in the western hills of Sichuan Province in 2003, the feature of runoff, sediment yield and the nutrient losses in different patterns of forest (bamboo)-grass compound management were analyzed.
通过坡面人工径流小区的定位观测,对川西低山区2003年几种林(竹)-草复合经营模式与农耕地的产流产沙特征及养分流失情况分析与比较,结果表明:①植被类型及土地经营利用方式的不同对径流特征及产沙量有很大的影响,苦竹+牛鞭草模式在3年后所表现的生态效益优于其他模式;②由于川西低山区强降雨主要集中在7、8月份,此两月各模式与农耕地的产流产沙量均达各自全年总量的70%以上。
2.
More importantly, features of surface runoff and sediment yield, nutrient losses and factors which influenced these features were discussed.
通过坡面人工径流小区的定位观测,在分析与比较川西低山区2003～2004年几种林(竹)+草复合经营模式与农耕地的植被生长状况、经营措施、土壤物理性质及林分持水性能的基础上,重点探讨了各基本模式与农耕地的产流产沙特征和养分流失情况及其影响因素,结果表明: 1 退耕种植的林+草、竹+草有别于其它生态林植被模式,也不同于农耕地的高强度干扰。
