At the same time, the quality of different - state water was studied. the results show : the soil bulk density of the fir wildwood heightens with the increase of soil depth, specifically 0. 74 > 0. 94 andl. 34g / cm3, the saturated, canaliculus and field moisture contents decrease gradually in layer a, b and c, accordingly the soil total foveola decreases gradually, and the moisture - hold capacity of the soil lessens gradually with the increase of the soil depth ; there is small difference of the soil bulk density between layer a and b in the outer space, which are respectively 0. 92 and 0. 99g / cm3, and the other laws are the same as the in ner in the main ; reverse success often occurs in the low position of the thoroughly - fell trace and plateau marsh is formed
結果表明：冷杉原始森林土壤容重隨土層深度的增加而增大，分別為0 . 74 、 0 . 94 、 1 . 34g cm ~ 3 ，飽和持水量、毛管持水量、田間持水量a層、 b層、 c層逐漸減小，十壤總孔隙度也逐漸減小，土壤的持水能力隨深度的增加逐漸減弱；林外空地a層、 b層十壤容重相差不人，分別為0 . 92和0 . 99g cm ~ 3 ，其它規律與林內人體相同：皆伐跡地的低洼地段容易發生逆行演替，形成高原沼澤地。 -
Through on - the - spot investigation and study of restoration of the function of water conservation, it ' s believed that under the underdeveloping circumstances of xinyang, comprehensive measures can be taken to protect key areas of water conservation and restore its vegetation step by step so as to reinforce its function, by transforming closely, establishing forbidden lumbering zone, planting grass in damp soil, spreading marsh gas and bringing low - lying beach land under control
摘要通過實地調查，對信陽市淮河源水源涵養功能恢復展開研究，認為在目前信陽經濟還不發達的情況下，可以首先對重點水源涵養區採取綜合性保護措施，通過封閉性改造、禁伐區設立、濕地種草、推廣沼氣等措施，逐步恢復涵養區植被、生態多樣性和生物多樣性，增強淮河源水源涵養功能。 -

Although investigations are just beginning, reed expects that katrina ' s surge pushed saltwater much farther into the marsh than normal. “ that salt has likely baked into the soil, ” reed says, “ and won ' t readily wash out, ” which could kill wide areas of marsh grass from the roots up
實際調查雖然才剛開始，但是利德預期，卡特里娜的巨浪異常深入地將海水推向沼澤內部， 「這些鹽份很可能會進到土壤里， 」利德說： 「而且不易被沖洗掉，大面積的沼澤草地可能因此由根部死去。 」
