| 1. | Numerous experiments have been performed to establish the erodibility of the soil . 许多实验都曾得出了土壤的可侵蚀性。 |
| 2. | It depends only on erodibility of the surface and tends to decrease as erodibility increases . 它仅取决于表面侵蚀程度,并且随侵蚀程度的增加而趋于减小。 |

| 10. | It divides the main vegetation of the headwater region of huangpu river into 4 categories based on field survey and observation and methods of factor analysis and systematic cluster analysis and according to the degree of soil and water conservation function : deciduous trees and shrubs are category 1 which shows very strong soil and water conservation function ; tea plantation , grasslands and pine trees are category 2 which has stronger function ; the category 3 is moso bamboos and broadleaved evergreen trees which have stronger permeability and erodibility , but the permeable performance is not outstanding , the capacity of soil moisture storage common and soil and water conservation function moderate and ; the category 4 is uncovered land where the soil and water conservation function is very weak and its permeability , erodibility , erosive resistance and soil moisture storage capacity are all notably smaller than that of the other lands 摘要在野外调查、实测的基础上,采用因子分析、系统聚类分析的方法,根据土壤层水土保持功能的强弱,将黄浦江源区主要植被类型分为4类:落阔林、灌木林为第一类,表现出很强的水土保持功能;茶园、草地、松林为第二类,土壤水土保持功能较强;毛竹林、常绿阔叶林表现出较强的抗蚀性和抗冲性,但渗透性能并不突出,土壤贮水能力也一般,水土保持功能中等,为第三类;裸露地水土保持性能很差,单独作为第四类,其渗透性、抗蚀性、抗冲性、土壤水库容都显著小于其他各样地。 |
