Typical rainfall effect on sediment loss and runoff of cash forest 經(jīng)濟林模式典型次降雨對泥沙和徑流流失的影響
To my knowledge these sediment losses from new roads in yunnan are the highest values ever reported 據(jù)我所知,這些新公路的泥沙流失率屬于有報道以來的最高值。
Soil is the base of agriculture production , the key measure to prevent water and soil loss is to conserve soil , but most soil nutrient is lost with the sediment loss , and serious water and soil loss make the soil thickness degrease , the soil nutrient be deficient and lean , the land quality degrade and the yield of plant decrease , all this results is going to threaten the people ' s transplanting and the agriculture sustainable development , and restrict the economy development of three gorges regions 同時,土壤是農(nóng)業(yè)生產(chǎn)的根本,治理水土流失的關(guān)鍵是要保住土壤,而土壤養(yǎng)分絕大部分是隨著泥沙流失的,嚴重的水土流失造成土層淺簿、養(yǎng)分貧瘠,土地質(zhì)量退化,產(chǎn)量下降,對三峽庫區(qū)移民工作和農(nóng)業(yè)可持續(xù)發(fā)展造成嚴重威脅,制約三峽庫區(qū)經(jīng)濟發(fā)展。因此進行三峽庫區(qū)坡耕地土壤侵蝕機理研究,探索減輕坡耕地土壤流失的方法措施,具有全局性的重大意義。
