【摘要】：城市与乡村的过渡景观是城乡一体化发展中形成的地域性生态界面,其表现形式主要是以植物为主,城郊植被与市区景观共同构建了城市的绿化系统。植物通过自身独有的光合与呼吸作用,对自然界的光能进行利用与转换,为城市创造了自然的物质流动、能量流动,为城市提供固碳节能、氧气供应、温湿度调节、减噪滞尘和雨水蓄存等功能。区域经济发展下,城市绿化模式不断延伸至远郊和农村,城乡绿化逐渐融为一体。绿量作为城乡生态的有效反馈对象,主要从叶面积指数、叶幕、三维绿量三个方面来论证。鄂尔多斯东胜区东部的铜川镇与塔拉壕乡交界沿线带为研究地点,气候条件、土壤条件、人文建设相对稳定,样方法进行绿地实测,建立样地14个,共54块主要绿地植物构成,记录43种植物的树高、冠幅、胸径、叶幕厚度等生长特征。CI-202便携式叶面积仪测量单片叶的周长、面积、长、宽以及长宽比率。最后选出国槐、新疆杨、白杜、白扦、樟子松、山杏、榆叶梅和大果榆作为基调树种进行研究。(1)以树高、冠高、叶幕厚度为参数,建立鄂尔多斯市东胜区铜川镇与塔拉壕乡沿线带国槐、新疆杨、白杜、白扦、樟子松、山杏、榆叶梅和大果榆的三维绿量方程。(2)八种植物在一定冠幅范围内的平均三维绿量排列:新疆杨(56.99m~3)国槐(22.13m~3)樟子松(13.31m~3)山杏(12.10m~3)大果榆(5.51m~3)白扦(2.34m~3)榆叶梅(1.14m~3)白杜(0.69m~3)。样本植物的叶面积平均指数为:新疆杨(233.96)大果榆(161.19)白扦(138.12)樟子松(18.09)国槐(15.81)榆叶梅(13.30)白杜(5.24)山杏(3.55),由数据可得出,植物的生长环境虽然相同,但冠层饱和度却明显不一样,也是植物在该地生长情况的间接反映。(3)建立三维绿量与胸径的二元回归方程,得出两者存在显著相关性,落叶树相关指数排列为:新疆杨(0.686)国槐(0.669)大果榆(0.586)白杜(0.341)榆叶梅(0.191)山杏(0.081);针叶树排列为:樟子松(0.684)白扦(0.261)。由此可见,说明植物生长过程中,干性强、层性明显的枝干对植物的三维绿量的关联性更大。(4)对此区域植物进行的量化统计,将不同树种的形态指标与三维绿量、叶面积指数等进行对比,归纳出本地主要的园林植物构成类型,客观考量当地植被选种的科学性与合理性。
[Abstract]:The transition landscape between cities and villages is a regional ecological interface formed in the development of integration of urban and rural areas, the main manifestation of which is plants. Suburban vegetation and urban landscape jointly constructed the urban greening system. Plants through their own unique photosynthesis and respiration to the use and transformation of natural light energy for the city to create a natural material flow. Energy flow provides cities with carbon sequestration and energy saving, oxygen supply, temperature and humidity regulation, noise reduction, dust retention and rainwater storage. With the development of regional economy, the urban greening mode extends to the suburbs and rural areas. The green quantity is the effective feedback object of urban and rural ecology, mainly from leaf area index and leaf curtain. Three dimensional green volume to demonstrate. East of Ordos Dongsheng area Tongchuan town and Tara trench township along the border as the research site, climate conditions, soil conditions, human construction is relatively stable, the sample method for green land measurement. A total of 54 main greenbelt plants were constructed in 14 plots. The growth characteristics of 43 species of plants, such as tree height, crown width, diameter at breast height and leaf curtain thickness, were recorded. CI-202 portable leaf area meter was used to measure the circumference of single leaf. Area, length, width and ratio of length to width. Finally, tree height and crown height were selected to study the tree height and crown height of Sophora japonica, Populus Sinensis, Dendu, Pinus sylvestris, Pinus sylvestris, Apricot armeniaca, Ulmus pumila and Ulmus pumila. The thickness of leaf curtain was taken as the parameter to establish Tongchuan Town and Tara trench Township in Dongsheng District of Ordos City with Sophora japonica, Populus sinensis, Baidu, Prunus sylvestris, Pinus sylvestris and Apricot armeniaca. Three dimensional Green quantity equation of Ulmus pumila and Ulmus officinalis) the average three dimensional green quantity of eight species of plants in a certain crown range is 56.99mS3) the Chinese Sophora japonica L. 22.13mS3) Pinus sylvestris var. mongolica (. 13.31mPU (3) Prunus armeniaca (12.10mPu)) Sanguisorba (5.51m)) Sangui (2.34mm3) Sanguis-leaf Plum (1.14m) (3) Bedu (0.69m ~ (3)). The average index of leaf area of the sample plants is 233.96) 161.19) (138.12) Pinus sylvestris var. mongolica 18.09) the Chinese Sophora japonica 15.81). 13.30) White Dudu 5.24) Prunus armeniaca 3.55). It can be concluded from the data that although the plant growth environment is the same, but the canopy saturation is obviously different, it is also an indirect reflection of the plant growth in the area. It is concluded that there is a significant correlation between the two. The relative indexes of deciduous trees were: Populus sinensis 0.686) Sophora japonica 0.669) Ulmus pumila 0.586) Prunus officinalis 0.341) Elm leaf Plum 0.191) Prunus armeniaca L. 0.081; The arrangement of coniferous trees is: Pinus sylvestris var. mongolica 0.684). It can be seen that there is a strong dryness in plant growth. The quantitative statistics of the plants in this area were carried out, and the morphological indexes of different tree species were compared with the three dimensional green quantity and leaf area index. The main types of local garden plants are summarized, and the scientific and reasonable selection of local vegetation is considered objectively.
