黑龙江省依兰县奋斗小流域经过20多年的综合治理,流域面貌焕然一新。这个小流域位于松花江右岸,是倭肯河流域的一条支沟,面积为3.68平方公里,属丘陵半山区,治理前水土流失十分严重。流域内只有天然次生林45亩,44条侵蚀沟把900多亩耕地分割成75块,60%的耕地裸露碎石,地力逐年减退,从1961到1963年,粮豆单产年均递减4—5%,人均收入只有99元。流域内的奋斗村1960年前欠国家贷款一万多元,是依兰县最贫困的村子。为了摆脱贫困,从1964年起他们改变过去单项治理,迟迟不见效益的 Yilan County, Heilongjiang Province struggling small watershed after more than 20 years of comprehensive management, drainage look anew. This small watershed is located on the right bank of the Songhua River and is a branch ditch in the Woken River basin with an area of ​​3.68 square kilometers. It belongs to the hilly half-mountainous area, and soil erosion before treatment is very serious. There are only 45 mu of natural secondary forest in the basin, and 44 erosion ditches divide 900 mu of cultivated land into 75 blocks and 60% of the uncultivated gravel land. The land fertility decreases year by year. From 1961 to 1963, , Per capita income is only 99 yuan. The struggling villages within the basin owe more than 10,000 yuan to the state loans before 1960 and are the poorest villages in Yilan County.
