| 7. | It is best that the stiffness ratio of ring beam to pile is 2 to 3 . we think over burying depth of piles is 30 % of the whole length when ring beam existing . but it is necessary to decide according to the quality of soil layers and types of piles 圈梁与桩的刚度比为2 3为最佳,有圈梁时桩的入土深度可以考虑占总桩长的30 ,但需要根据具体的土层性质和桩的类型斟酌而定。 |
| 8. | The types of vegetation influence the size and quality of soil organic matterr . the spatia - temporal of soil loc pool under various types of vegetation as affected by human practice is necessary for assessing the alteration of soil quality 不同森林类型,由于其凋落物数量、类组及分解行为不同,因而形成的土壤碳库大小与特征将存在较大差别,林地不同利用特别是强度利用后,土壤活性有机碳库将会发生较大变化。 |
| 9. | Through field investigation and laboratory analysis of social - economic data , the results were attained as follows : land use structure has a trend to be stable ; the agricultural inputs of labor and capital and the income of agriculture are increasing ; the quality of soil is improved ; the pollution of water and soil are controlled within standard 本研究通过野外调查和实验室分析,结合分析多年的社会经济统计数据,揭示了平谷区农用土地利用变化的特点:土地利用结构趋于稳定;劳动集约和资金集约相结合,土地集约化水平较高;土地生产率和经济效益都在提高;水土资源质量还在安全范围内。 |
| 10. | On the other hand for four main vegetation typies , which are picea crassifolia , forests sabina przewalskii forests , bushes and pastureland , whose soil permeability function was analyzed from angle of its physics , capacity of water , storing water in it . the results show as follow : permeability function of soil is controlled by quality of soil hole . the quality and quantity of soil hole under picea crassifolia forests are the best , and the permeability also is the best 另外,从土壤物理性质、蓄水量、贮水量等角度对祁连山苔藓云杉林、祁连圆柏林、亚高山灌丛林、牧坡草地4种主要植被类型的土壤渗透功能进行分析,结果表明:土壤的渗透功能主要由土壤非毛管孔隙度的质和量决定的,苔藓云杉林土壤非毛管孔隙度的质和量最好,它的渗透也最好;虽然亚高山灌丛林的渗透功能次之,但由于它所处的位置和面积大,现实贮水量在祁连山四种主要植被类型中最大。 |
