62. Properly managed forests prevent flooding and soil erosion, and stabilize climatic conditions.

63. We can use soil erosion model and nomogram to calculate soil erodibility.

64. Universal Soil Loss Equation (USLE) is an empirical model widely used in the domain of soil erosion by water.

65. The characteristic of soil erosion in the eastern part of Guizhou were expounded. The primary questions are the petridesert in karst area and the soil erosion in tung tree forest region.

66. What it really means is "no moldboard plow" and because of that we are supposed to believe that farmers are controlling soil erosion.

67. Therefore, in order to construct the first defense line for soil erosion, low benefit value zone which locates in Kuyehe River basin and Huangfuchuan River basin is commanded to be selected firstly.

68. Drought and soil erosion had long been a major problem.

69. Soil erosion load estimation is one of the key issues in soil erosion research.

70. Because the soil and water conservation factor was not concluded in net method, the soil erosion modulus calculated with net method was higher than that calculated with sampling survey method.

71. Especially in the near decades, these reasons result in a series of ecological problems, such as pasture retrogression, vegetation sparsity ,(sentencedict.com) soil erosion and dust devil.

72. It was found that soil erosion resistance increased with the number of plant roots, though no consistent quantitative functional relationship was observed between them.

74. The development of the soil erosion model can be divided into empirical model, physical process model and distributed model period.

75. Land resources are dwindling because of water loss and soil erosion.

76. The results reveal that land desertification, steppe degeneration, secondary soil salinization or alkalization, soil erosion and air pollution in urban areas are the most serious entironment problems.

77. Results show that soil and water conservation measures have played an important role and soil erosion prevention and control reach the target value.

78. The rock physics mechanics property is bad, weathering and the soil erosion are mightiness.

79. Nongzhong loess hilly a brittleness ecology environment with a sparse vegetation cover and severe soil erosion.

80. The erosive rain is defined as rain(sentencedict.com), which can cause soil erosion.

81. The best way to undo the problem of soil erosion is to reforest the cultivated land.

82. Soil erosion which is called"peristaltic disaster"is one of the most common and the strongest geological disaster in human society nowaday.

83. For these areas, terracing or strip cropping could be suitable to reduce soil erosion . 7.

84. The low resistant erosion ability of ground substance, especially in granite weathering crust and purple rock and its soil are the inner causes of severe soil erosion.
