园林绿地养护与管理技术 总被引:1,自引:0,他引:1
园林绿地建成后,经常性的养护管理对绿地整体效果的影响十分重要。应根据树木在园林景点中的用途、不同季节的需要进行养护,原来种植的树木,树干已摇动的应填土培实,倾斜歪倒的应抓紧扶正, 相似文献

作为基础设施的重要组成部分,园林基础设施的开发与提高城市的环境质量息息相关。目前,园林绿地已成为我国基础设施和改善自然环境的重要组成部分,与人们的日常居住环境有着密切的联系。在园林工作中,害虫对树木的健康有着很大的危害。因此,需要积极的开展相应的病虫害控制工作,以此提高园林绿地管理水平显得尤其重要。该文的主要目的是对园林绿地和管理中病虫害防治的技术进行简要的分析和科学的探讨,以确保树木能够健康生长,提高城市的园林绿地水平。 相似文献

The importance of ecological benefit analyses about green space systems has been widely discussed on the basis of a per-ceived bias towards the landscaping effect of green spaces to be built in urban areas as opposed to the perception of comprehensive ecological benefits of designed plant communities. Given the basic principle of ecological benefit analyses and evaluation methods widely applied today, the methodology to calculate ecological benefits and to model the expansion of urban green spaces by CITY-green 5.0 and its conditions for application were explored. We propose that aerial images can be substituted by AutoCAD graphics of a green space containing detailed information of plant dispositions by digitizing the key features during the working process in order to evaluate the ecological benefits quickly and to offer proper guidance to the establishment of small scale green spaces in urban areas. The theoretical foundation, potential application range and prospects for extension of the method are introduced by using the analysis of ecological benefits of the green spaces on the campus of Southwest Forestry College, Kunming, as an example. 相似文献

Abstract The English yew (Taxus baccata L.) is an endangered rare tree species in Austria. More than 600 bud samples were collected from seven populations in three regions of the Eastern Alpine mountains for estimating their genetic structures by using isozyme gene markers. Nine gene loci encoding for seven enzyme systems were investigated. The revealed 32 alleles indicate a higher multiplicity of the east alpine gene pool compared with other European regions. English yew showed a high level of genetic variation, with a mean number of alleles per locus (A/L) of 2.7. A total of 76.4% of the loci were polymorphic, the average expected heterozygosity was (H e) 0.274 and the mean observed heterozygosity (H o) was 0.238. The relative proportion of genetic differentiation among the regions was found to be 6.2%, the level of gene flow was high (Nm=3.78) and the level of inbreeding (0.130) among the regions was medium. The obligatory out crossing (dioecious plant), the long generation time, the ability to regenerate from stump and the seed dispersal by birds and rodents might contribute to the high level of genetic variation found within the population. The conservation propositions are discussed with respect to the genetic structure and the poor recruitment of this species. 相似文献
