摘要: <正>以大连市为例,探讨了城市化过程中城市人工地貌演变特征及其与经济驱动因素的关系。笔者利用Surfer 8和MapInfo7.0定量研究了城市人工地貌在时间序列上的演变,借助SPSS分析了经济驱动因素与此种演变的关系。结果表明:大连城市人工地貌的增长总量与经济发展呈正相关;1990年以后城市人工地貌总体进入快速增长时期,在经济发展的推动下,高级和中级城市人工地貌发育规模和速度呈大幅度增长,城市迅速“增高”和“高低”起伏现象突出,对城市景观整体性将构成影响。

Abstract: It was a time consuming process if technique of paraffin section was used to observe plant specimen because fussy processes such as dehydrating, infiltrating and embedding were needed before being observed. Cryo-sectioning technique was used to observe leafstalk, leaf, stem and root structure of Schisandra chinensis (Turez.)Ball.. The operating process was simple and efficient. Clear image could be acquired within one day. The crucial step were to select a proper concentration of glycerol, a suitable temperature of freezing and an appropriate way of section-flatting.
