本論文提出老化混凝土板的分層彈性理論，對混凝土結構的承載能力的影響進行分析；對浙江沿海混凝土結構及其構件的抗彎、抗剪、粘結性能以及結構的動力性能進行分析研究；提出了影響沿海混凝土結構耐久性的主要因素一混凝土的碳化作用，堿骨料反應，混凝土的腐蝕機理以及鋼筋混凝土中鋼筋銹蝕的影響因素。Vegetation restoration also resulted in the changes of soil physical and chemical properties, i. e., the contents of organic matter, alkali - hydro nitrogen, rapidly - available potassium and the contents of fine sand, very fine sand and clay were increased significantly, while ph and the content of rapidly - available phosphorus were decreased
植被的恢復使土壤理化性質發生了變化，與恢復前相比土壤中有機質、堿解氮、速效鉀以及細砂、極細砂、粉砂、粘粒含量顯著增加， ph值和速效磷含量降低。The results are mainly as follows : sticky quality, tuber structure, the loose and tense degree, unit weight, ph value ( decreases in the few conditons that resulting acidity strengthening ), alkalinity increases in the same soil level, root quantity and macro - element content decreases ; there has a extraordinary difference between k, ca and mg, especially for pb and cd which shows that the collecting function of soil enhances under the disturbence conditon, and other micro - elements, such as zn > mn, cu, ni get decreasing. tourism activity is one of the key reasons for water body pollution. to different recreation types, the pollution degree has the obvious difference
各景觀區所取樣點中，土壤理化性旅遊破壞區所受影響最大，呈現出質地粘重、結構變差（以塊狀為主） 、同一層次土壤松緊度增大、根系變少、容重增大、土壤ph值增大（也有個別ph減少，以致酸性增強） 、堿性增強、大量元素降低，其中對k 、 ca 、 mg影響中有顯著性的差異（又以游道類影響最為顯著） 、重金屬元素（ pb和cd ）明顯增多、顯著性的差異最為明顯，其它微量元素（ zn 、 mn 、 cu 、 ni ）逐漸減少，表明旅遊活動干擾後土壤對pb和cd富集作用增強等特點。分享友人
