新疆水土流失经济损失计量研究

新疆维吾尔自治区的能源开发加剧了水土流失，使得本就脆弱的生态环境显得越发脆弱。水土流失不仅使国民经济蒙受重大损失，也对公共安全、生态安全和土地资源、水资源保障构成巨大挑战。本文依据新疆水利厅提供的数据，从土壤养分流失价值、水源涵养损失、土地资源废弃损失和作物减产损失等四个方面，对新疆雏吾尔自治区的水土流失带来的经济损失情况进行定量分析，得出2000年新疆雏吾尔自治区水土流失造成的直接经济损失高达354．51亿元，造成的水库渠道淤积损失458．89亿元和对水环境的影响51．6213亿元，为从水土流失带来经济损失的角度核算能源开发水土保持补偿标准提供了重要依据。

The measurement of economic loss of soil erosion in Xinjiang

Energy development in Xinjiang Uygur Autonomous Region has increased soil erosion, makes the fragile ecological environment become more vulnerable. Soil erosion not only does the national economy suffer significant losses, but also poses a huge challenge for public safety, ecological security, land resources and water resources. According to data provided by the Department of Water Resources in Xinjiang, this article makes quantita- tive analysis on the economic losses caused by soil erosion in Xinjiang Uygnr Autonomous Region, which from the value of the loss of soil nutrients, loss of water resources conservation, loss of land resources waste and crop production losses. We estimated the direct financial losses caused by soil erosion in 2001 in Xinjiang Uygnr Autonomous Region amounted to 35. 451 billion yuan, the reservoir channel siltation loss is 45. 889 billion yuan and on the wa- ter environment is 51. 6213 million yuan. It may be used to make soil and water conservation compensation standard in energy development project from the point of economic loss measurement of soil erosion.
