The results showed that soil wind erosion was the near-surface wind-sand activity. The sediment particle saltates mainly in 7.5-43.5 cm. Wind sediment amount decreased along height, which correlate well with power function, exponent function and logarithm function. The sediment particle composition was influenced strongly by wind erosion intensity and topsoil characteristics. However, the regularity of sediment composition was distinct in a definite paticle size in different heights. Wind erosion amount increases with wind speed exponentially, which was influenced by times that the wind does.

The hilly part of the loess plateau is one of the most severely eroded regions of the loess plateau.

基于此本论文选择陕北大理河流域为对象，依据黄河支流的水文资料，分析了不同尺度大小流域的水沙侵蚀资料，取得以下结果：(1)发现就次暴雨洪水而言，各尺度流域出口的径流泥沙过程都表现为洪峰陡涨陡落沙蜂陡涨缓落，含沙量随流量增大到一定程度1.27m／s时变化趋于稳定，保持在400kg／m~3以上，决定了该地区水沙之间的关系，不同尺度大小流域出口暴雨洪水的水沙关系在一定程度上是一个区域特征值。

Based on the analysis on the character of MPDI, the relationship between NDVI and MPDI is studied, and the threshold value of MPDI under densely vegetation covered, middle vegetation covered, sparse vegetation covered and nudation are built. MPDI＞0.12 means the surface is desert,sand or rocks; 0.01＜MPDI＜0.12 means the sureface is covered by middle vegetation, and MPDI＜0.01 means the earth is covered by densely vegetation. 4. Based on the expirical model relation between MPDI and vegetation optical thickness, the latter is computed by the modified algorithm.

The results showed:Under the same fertilizer consumption,covered with straw and covered with film can increase the chlorophyll content and total leer area duration of the maize,can improve leaf nitrate reeducates activity,Photosynthesis and roots vigor,and the nitrate reeducates activity,the chlorophyll content and the roots vigor present positive correlation with yield. Meanwhile,average dry matter accumulation of straw-covered increased 7.1% than this of no-ploughed,yield increased 15.3%.The average dry matter accumulation of film-covered increased 20.1% than which of no-ploughed and 12.1% than which of plough and covered with straws.And yield increased 26.8% and 10.1%,notable differences.

结果表明：在相同的肥料用量条件下，秸秆覆盖和薄膜覆膜对玉米生长发育具有良好的促进作用，能显著增加玉米叶片叶绿素含量和光合势，增强叶片硝酸还原酶活性和根系活力，同时玉米叶片硝酸还原酶活性、叶绿素含量、根系活力等与最终籽粒产量呈正相关；秸秆覆盖比免耕全生育期平均单株干物质积累量增加7.1%，籽粒产量增加15.3%，薄膜覆膜分别比免耕和翻耕残茬覆盖全生育期平均单株干物质积累量增加20.1%和12.1%，最终籽粒产量增加26.8%和10.1%，差异显著。

And it has given the effects of the all factors on the runoff by 1D river networks mathematical model. Due to the natural and artificial influences, the water-sediment transport has greatly changed. It is characterized by marked decrease in runoff and sediment diverted from these outfalls and increase in water-sediment transport of main stream. The key factors causing these changes are aggradation of the three outfalls channels and Jingjiang river cutoff work.
