  1. 2. the structure of purple soil is meliorated by sabaigrass. when contrast to bare land treatment and natural wild grassland treatment we knew that sabaigrass treatment and grass tree solid plating treatment reduced soil bulk density, enhanced soil capillary porosity, non - capillary porosity and porosity ratio, decreased soil sand grain content, enhanced soil clay grain and silt grain content so as to reduced the dispersal degree of soil, improved the aggregate capacity of soil, increased the amount of soil aggregate structure, meliorated the water permeability of soil, accelerated the form of good soil structure

    龍須草能改善紫色土的土壤結構龍須草純種植被和林草立體種植植被能不同程度地降低土壤容重,減少土壤砂粒含量,增加土壤的毛管孔隙度、非毛管孔隙度和孔隙比,以及增加粉粒含量,從而降低土壤分散度,提高土壤團聚性,增加土壤團粒結構數量,改善土壤的透水性,促進良好土壤結構的形成,最終提高土壤的蓄水保肥性能,增強土壤的抗蝕性和抗沖性。
  2. The product quality faces up to enormous domestic and international markets challenge and the peasants face up to the slow increasing of their incomes. the shortage of water resource is more serious for the planted system, climatic change and low utilization ratio. cultivated land resource is reducing rapidly for nature factors and urbanization process, etc. the analysis results indicate the resour ces utilization mode in the hhh plain is still high investment, high - energy consumption, and grievous pollution

  3. The middle and lower parts of woodland and grassland had higher soil water contents during rainy season, which resulted from smaller evapotranspiration and more infiltrated water with a lower gradient. however, upslope runoff infiltration was another reason for hillslope with a lower cover ratio, such as bare land

    雨季林草地坡中下部土壤水分含量較高的原因,可能主要與其蒸散較小且坡度較緩導致入滲水量較多有關;但是對于植被覆蓋度較低的坡地(如裸地) ,坡中下部土壤水分含量較高還與上方來水有較大的關系。
  4.

  6. ( 2 ) runoff - yielding time on grassland with a higher cover ratio primarily depended on initial water content, and their relationship might be described by a power function too. surface crust could easily take place on bare land, so its runoff - yielding time primarily depended on rainfall intensity, and their relationship might be described by a linear function

    ( 2 )植被覆蓋度較高的荒草地,產流時間主要取決于初始含水量,兩者的關系可用冪函數描述;裸地因降雨產生地表結皮,產流時間主要取決于降雨強度,兩者的關系可用線性描述。
