To improve the purple soil storage capacity, to prevent soil erosion in hunan province, the choice of HengYangXian 20o purple soil slope, setting Guan waste land, grassland, natural forest and grassland and agrimony slight composite 4 processing, the water treatment performance and its mechanism, and the results show that, compared to the purple soil LuoDe HuangShanPo ground implement agrimony and three-dimensional planting trees for 1-2 years later, reduce soil bulk density 0.10 g/cm3 0.09 ~, soil porosity, permeability of soil moisture 14.01% increase rate increase 2.20 ~ 2.29 times.

In the dry land and garden plot, the soil eroding amount of terraced fields is only 1/3 of that be ploughed directly along the slope. It is difficult that assart along the contour in the dry land and garden plot, after the first 1~2 years, the soil eroding amount will increase at double. From the soil and water conservation point of view, the mode that integrates arbor, shrub and grass in woodland is the best, the mode that plants grass in bare land is the second.
等高作梯的旱耕地和园地土壤侵蚀量仅为顺坡直耕的早耕地和园地顺坡的1/3左右;早耕地、园地等高开垦的强度大,开垦之后1~2年土壤侵蚀量成倍增长;从水土保持角度看,林地乔、灌、草结合模式最好,裸地植草模式次之。

There were four treatments on the hillside: artificial forest with underbrush, artificial forest without underbrush, planting tea bush on contour terrace, barren on contour terrace. The runoff depth, runoff index, water loss, soil erosion and soil organic matter erosion to the 4 treatments during 4 rainfalls were determined by using the Runoff Collector.
试验设计了人工林下地表覆盖、人工林下地表裸露、等高梯田种植茶树和等高梯田裸地对照4个处理,采用自制的径流收集器分别测定了各处理4场降雨的径流深度、径流系数、水土流失量和侵蚀量等指标。

The former include the ways of seeds dispersal, the adaptation characters to exposed lands, relationships between species and so on. The species that transmit seeds by wind and adapt the environment of the primary lands more quickly can become the first colonizer of exposed lands, and some microbes play an important role in the colonization of plants.

The saving-water effect of Radish and Cabbage under PFM and appropriate irrigation,and the drought-resisting of radish seedling which seed was soaked by CaCl_2 were systematicly reseached by field observation and the experiment in door.The main results were summaried as follows:The soil temperature of 0~20cm cultivated layer was increased 3-4.5℃ in early growth period was only 1℃ in late growth period by PFM;there was more water saved up to 20.84mm in 0~60cm soil layer by PFM than no PFM in the early growth period of Radish;the yield and water use efficiency of Radish in L4 were exceeded respectively 10.1% and 21.9% of that contrast, the yield and water use efficiency of Cabbage in G4 were exceeded respectively 8.7% and 26.58% of that contrast, under PFM and appropriate irrigation.
主要研究结果如下:地膜覆盖在植株生长前期耕作层平均可增温3~4.5℃,在生长后期增温幅度减小,仅有1℃左右;地膜覆盖在植株生长前期可有效的保持土壤水分,在萝卜生长前期,使0~60cm土层内多储水20.84mm;在覆膜不灌水充分利用自然降雨的条件下生产萝卜,可比裸地正常灌水萝卜增产10.1%,水分利用效率提高21.9%;覆膜只浇一水生产甘蓝,可比裸地正常灌水生产甘蓝增产8.7%,水分利用效率提高26.58%。

The result indicates that the water, tundra, residential sites, needle-leaved forest and brass were decreased from 1977 to 1985; while the plantation and the coniferous and broad-leaved mixed forest obviously increased; and the broad- leaved forest, betula ermanil forest, road and bare soil also increased. During 1985 to 1999, the water, bare soil, coniferous and broad-leaved mixed forest, broad-leaved forest reduced, the rest landscape types increased in this area.
分析表明:从景观面积变化率来看,1977~1985年间,水体、苔原、居民点、针叶林和草地的面积减少,耕地和针阔混交林的面积增加显著,阔叶林、岳桦林、道路、裸地增加;1985~1999年间,水体、裸地、针阔混交林和阔叶林的面积减少,其他类型面积增加。

Although forest canopy layer could prevent splash erosion effectively, clay was taken away by overland flow and run off easily, the erosion amount became less after removing the forest canopy and surface soil, while the splash erosion still produced in the surface layer; the splash function weakened after having water current, the starting particles were less than bareland, so removing the surface disturbed soil made the erosion amount and clay less, silty sand more than bareland, but unsteady, the wear and tear energy used by raindrop splash and current function for overcoming sediments separating and starting were comparatively large, sediments were very difficult to be started and transported, it explained that forest root systems could increase anti-erosion capability of forest vegetation, make rainfall-current system splash and export finer particles than bareland.
虽然林冠层能有效防止溅蚀的发生,但坡面流还是能带走粘粒部分,粘粒还是容易流失。去除林冠和表层土后,侵蚀量变得更少,但表层还是会被溅蚀,有水流后,溅蚀作用减弱,颗粒起动的比裸地的少,所以,去除表层扰动土后,侵蚀量更少,粉沙多,粘粒比裸地更少一些,但不稳定,雨滴击溅和水流作用用于克服泥沙分离起动损耗的能量较大,很难被起动输移,这说明森林植被根系的作用增加了林地植被的抗蚀力,使降雨一水流系统仅能溅起输出比裸地坡面更细小的泥沙颗粒。
