Mainly belonged to Loranthaceae. Plants of Phacellaria Benth. and their hosts were mainly distributed in tropical and subtropical area. Plants of Phacellaria Benth. maybe originated in tropical area in the south of China before Tertiary. Their ancestors were parasitic on ancestors of some plants of Loranthaceae by chance during Tertiary. It took them millions of years to form a sturdy relationship between parasites and hosts. Ph. rigidula was a hemi-parasitic subshrub. In area observed, its host was mainly Taxillus caloreas var. fargesii.

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.

结果与讨论：下阶梯背重率达10％时，膝关节著地瞬间角度、髋关节角位移、重心垂直位移均达到显著差异(p＜。05)；当背重率达20％时，垂直分力与其产生时间、最大负荷率、踝关节肌肉力矩与角劲度亦达到显著差异(p＜。05)，此时人体必须透过增加踝关节角位移机制来降低垂直地面反作用力和最大负荷率及延后垂直峰值产生时间，藉以减少地面反作用力对人体所造成的冲击；而重心垂直位移也受到背重的影响而增加，以上均显示背重对人体下阶梯时下肢的负荷与影响。
