The paper introduces the biological characters , sorts and functions of climbers , and the application of the vertical afforesting landscape design to modern city 摘要文章介绍了攀缘植物的生物学特性、类型、作用及在现代化城市中垂直绿化景观设计的应用。
In order to provide scientific evidence on the ecological aftereffect of uv - b radiation , this dissertation uses climbing plants to investigate the effect of uv - b radiation on them under greenhouse and field conditions . effects of uv - b radiation on trchosahthes kirilowii maxin seedlings in greenhouse - grown were first investigated 本文以攀缘植物为材料，初步研究在温室条件下和田间条件下增加uv - b辐射对其影响，为预测uv - b辐射增加所产生的生态学后果提供科学依据。
This is so because climbing plants are likely to encounter intensive - changing environmental condition during their growth ( especially change of illumination ) . secondly , there is a large proportion ( 30 - 40 % ) of climbing plants which belong to dioecism , and hence a gap between male and female plants on morphology , biological characteristic , economic value and so on . this dissertation focuses on herbaceous climbing plants , perennial or annual species such as dioecious trchosahthes kirilowii maxin and dioscorea opposita thumb , and monoecious luffa cylindrical ( l ) roem , it attempts to discover how climbing plants adapted to various environments and the mechanism of adaptation from aspects of physiological and reproductive ecologies at present , due to overuse of chlorofluorocarbons ( cfcs ) , the ozonosphere has become thinner and thinner , and the ultraviolet - b ( uv - b ) radiation has increased considerably 而攀援植物本身是一类理想的植物行为生态学研究材料：第一，攀缘植物由于受攀缘能力和支柱木资源的限制，在生长过程中通常要遇到强烈变化的环境条件(特别是光照) ；第二，攀缘植物中具有较高比例的雌雄异株类型，通常占地区攀缘植物种类的30 40左右，不同性别的植物在形态学及生物学特性、经济价值等方面存在一定的差距，因此，本文以雌雄异株攀缘植物栝楼( trchosahtheskirilowiimaxim ) (葫芦科多年生草质藤本植物)和山药( dioscoreaoppositathunb ) (薯蓣科薯蓣属植物) 、雌雄同株异花攀缘植物丝瓜[ luffacylindrical ( l ) roem ] (葫芦科一年生攀缘草本植物)为材料，试图从生理生态学及生殖生态学角度揭示攀援植物如何适应不同生境及其机理。
