The stronger lossing area above-mentioned is 30.7% of the total area. From 1950's to now, the soil and water loss in the upper reaches of the Yangtze River has been aggravated, but only in recent years it has begun to be...             长江上游水土流失面积共35.2万平方公里,占总土地面积的35％。在35.2万平方公里中,轻度流失区占37.8％,中度流失区占31.5％,强度流失区占20.5％,极强度流失区占7.4％,剧烈流失区占2.8％。流失较严重的强度以上的流失面积占30.7％。五十年代至今,长江上游的水土流失经历了一个断续加剧和近几年来开始有所缓解的过程。总的结果是破坏大于治理,水土流失面积和流失量均有所增加。以输沙模数区分,每平方公里从数十吨到数千吨不等。直门达以上江源地区,每平方公里年输沙模数68吨为最小,白龙江中游立节至武都干流区间,年输沙模数4,437吨为最大。有的区域或个别年份的输沙模数更大。30年来,由于受多种因素的影响,长江上游有的河段和支流的沙量有增加,有的并未增加甚至有减小的趋势,更多的则是分时段有增有减,呈不规则的周期变化;往后也不会出现本质性的变化。当前的水土流失治理进度和成效,与艰巨的治理任务相比,显得十分缓慢而极不相称。近年来,这种一方治理、多方破坏的局面不改变,生态好转将永无尽期。 文摘来源          According to the characteristics of uneven spatial distribution of precipitation and runoff and sediment yield concentrated usually in a flood season of the three rivers of Tuwei, Kuye and Gushanchuan. an empirical model of annual occurrences of runoff yield and sediment transport has been established by using a method of taking the maximum precipitation, rainfall intensity and geomorphological parameters of time interval within each element area a...             依据秃尾河、窟野河、孤山川三条河流域降雨时空分布极不均匀及产流输沙多集中汛期的特点,将流域分为若干单元,以各单元面积内的时段最大降雨、雨强、地貌参数为影响产流输沙综合指标,最后叠加成总指标的方法,建立了产流输沙次和年经验模型。统计结果表明,模型计算与实测值相比,平均相对误差分别为:年清水模数0.69％～4.5％;年浑水模数0.2％～8.4％;年输沙模数0.05％～11.5％。 文摘来源   << 更多相关文摘         相关查询: modulus of modulus of congruence modulus of convexity modulus of logarithm modulus of quadrilateral modulus of casting modulus of rotundity modulus of bending modulus of determinant influence of modulus loss of modulus predication of modulus  对查询结果不满意
