英文摘要 | This work aims to assess soil erosion induced nutrients loss in Xiaojiang River basin and to explore an appropriate approach to soil nutrients assessment. The content of organic matter, total nitrogen (TN), total phosphorus (TP), and total kalium (TK) of 44 surficial soil samples indicated lean soil in this basin. Moreover, soil nutrients of forest land, grass land, paddy land, shrub land, and slope farmland decreased in turn. Considering the enriching impact of fine material of sediment delivery, nutrient loss intensity of organic matter, TN, TP, and TK in different land types were made referencing to their erosion modulus. And then it was confirmed that organic matter, TN, TP, and TK transported and lost 145×103 t, 6860 t, 3715 t, and 19,850 t per year, respectively, and whose 20–30% were delivered into Jinsha River. Moreover, using the revised model and soil erosion data, the assessment map of nutrient loss was made and showed that intensive nutrients loss occurred in 1605 km2 land, accounting for 54% of the total, which should be taken as the key of soil nutrient conservation. |
