摘要:
采用基于3S技术的定量遥感方法，对1998年和1999年金沙江一级支流龙川江上游小流域进行了水土流失动态监测和防治决策分析。结果表明：1999年为涝年，侵蚀总量高达869008.97t，强度及其以上侵蚀级别的侵蚀量占总量的86.39%，侵蚀模数平均为7703.87t/km2。1998年为旱年，流失情况较1999年的轻微。1999年中度及其以上侵蚀级别的侵蚀面积占流失总面积的32.41%，而1998年只占26.09%。1999年需要治理和急需治理的面积占侵蚀总面积的15.45%和0.82%，而1998年的治理面积较低。本研究采用的技术在国内具有先进性和快速、准确、经济等优点，在云南山地有广阔的运用推广前景。
Abstract:
Within this project, a dynamic system for soil erosion inspect,based on 3S technology, was established.Using the system,a dynamic inspect of soil erosion was made during the year 1998 and 1999 in the area concerned,as well as an attempt of decision-making analysis of erosion protection and treatment.The studying region was in the mini-drainage area of up-stream of the Longchuang River,the main stream of the Yangtze River.As the inspect results showing,it was a waterlogging year in 1999,the gross of erosion in the region reached 869 008.97 t;the erosion amount at intensity level of intensive and above, took 86.39% of the gross;and the erosion module averaged 7 703.87 t/km2.It was a drought year in 1998,however,the extent of soil erosion was lighter than that in 1999.The total erosion area in 1999 at intensity level of moderate and above took 32.41%,and it in 1998 only took 26.09%.As the results of decision-making analysis indicating,the treatment area required for soil erosion control was 354.45 and 317.77 respectively in 1999 and 1998.The urgent treatment area was 18.91 and 17.96 respectively in 1999 and 1998.
