| 9. | The soil physical properties have obvious vertical distribution characteristic in the slope . the bulk density in sunlit slope is greater than it in sunless slope , and change in the follow order in the slope : top < middle < lower . while saturated soil moisture , field capacity , and wilting moisture are on the contrary
在地形上，土壤物理性质具有明显的垂直分布规律，阴坡除土壤容重外，饱和含水量、田间持水量和萎蔫湿度均大于阳坡；同一坡度和坡向下，容重从坡下向坡上递增，饱和含水量、田间持水量和萎蔫湿度均从坡下向坡上递减。 |
| 10. | Severe fires can often cause changes in successional rates and soil hydrologic functions , degradation of soil physical properties , alter c : n ratios , and result in subsequent nutrient loss through accelerated erosion , leaching or denitrification , and alterations in microbial populations and associated process can occur
高强度火烧往往能引起演替频率的改变，土壤物理性质退化，水文功能发生改变，改变c n比，加剧侵蚀、淋溶和反硝化作用，导致养分流火，微生物数量及其相关过程发生变化。 |
