采用土体损失、水分损失、养分损失(N,P,K,有机质含量)及泥沙滞留损失和泥沙淤积损失等5种实物型损失作为水土流失经济损失的评估指标,在全省土壤侵蚀调查基础上估算出湖南省及其各地水土流失经济损失的货币值。结果显示,湖南省水土流失的经济损失巨大,2000年全省水土流失经济损失货币总值达99.51亿元,占当年全省国内生产总值的2.73%,相当于全省农业总产值的11.35%,构成全省人均损失151.65元,农业人均损失212.72元,平均每1 km~2水土流失经济损失4.65万元。其中,养分流失是湖南省水土流失经济损失的主要形式,占损失总量的75.12%;中度侵蚀类型造成的水土流失经济损失最为严重,占总量的68.51%;与19...

Based on the present situation of the serious soil erosion in Hunan province, five kinds of material loss brought by soil erosion,including the soil detained and deposited, nutrition （the amount of N, P, K, and organic matter）,water and land loss, are chosen as the index to measure the economic costs of soil erosion. The results showed that the total economic costs of soil erosion reached 99.51× 10^8 Yuan in 2000,for 2.73% of GDP and 11.35%of agriculture output values in Hunan, being equal to loss 151.65 Yuan for everyone in whole Hunan and ...
