生态园林是园林可持续发展的根本出路。景观生态学中“斑块”、“廊道”、“基质”、“结点”等概念为城市园林绿地系统的整体描述提供了手段，把园林绿地与整体的城市景观联结起来，赋予新的内涵。城市中的绿地可视为散落在城市中的绿色斑块，只有通过建立绿色廊道使其连续才能构成城市自然生态的绿色景观系统，实现人类生态环境的可持续发展。 相似文献

城市湿地公园是城市重要的基础设施，具有十分重要的社会效益和生态作用。它能改善人类生存环境，保持城市良好的生态条件，创造舒适优美的园林环境，丰富人民群众的文化生活。因此在城市湿地公园规划设计中，除考虑满足教育功能以及生态保护方面的需求，还要特别关注对于景观美学的追求。景观美学主要通过自然景观资源整合以及人工设施如建筑、园林小品设施形态与构造与周围自然景观相结合所形成的景观艺术效果来体现。坚持园林绿化量质并举的方针，以乔、灌、藤、花、草相结合，构成多品种、多层次植物的绿地，最大程度地发挥城市园林绿化的作用。 相似文献

城市是人类聚居从事生产、生活和社会活动的特殊的生存环境.自十九世纪末叶以来,生产力迅猛发展,人类为了生存和发展,每日向自然界索取资源和能源,如开采矿石、石油、砍伐森林、占用耕地等.在大量消耗自然资源的基础上,人类文明取得长足的进步,但随之而来的与人类生存环境密切相关的空气、土壤和水体等遭受严重污染,自然的生态系统被破坏、全球气候变暖、物种消亡等现象的出现,使人类健康面临着严重威胁,这使人类不得不进行深刻的反思:人类如何才能与自然界和谐共处?
城市园林绿化不仅是对城市中原有的自然环境部分的合理保护与提高,园林绿化更是在城市这个人工环境中对自然环境的再创造,是对园林植被(花、草、树木)这种能够塑造自然空间的资源在城市人工环境中的合理再生、扩大积蓄和持续利用.于是,加强城市园林绿化建设就成为一项关系城市可持续发展的急切任务. 相似文献

随着安宁市城市化进程深入,大工业企业不断涌入,城市环境问题日益加剧,园林绿地系统作为庞杂的城市系统中唯一具有自净功能的组成部分,在维护生态平衡、美化景观以及改善环境质量等方面的重要性更加凸显,建设生态化、可持续发展的节约型园林绿地是当前城市绿化工作的当务之急、重中之重。本文探讨了安宁市节约型园林绿化建设中存在的问题和对策。 相似文献

草坪与园林在城市的园林绿地建设中有关好前景，中国园林虽然具有西方优秀艺术作品难以企及的精巧之处和意境关，但草坪绿地比例太少。改善城市生态，创造适宜的生活环境，最有效的手段就是健全城市的园林绿地系统，在花园中建设城市。扩大草坪绿地面积，充分发挥草坪的生态和环境功能，同时发扬中国园林独特的艺术魅力，使中国的园林事业实现质的飞跃。 相似文献

现在是生态失调困扰人们的时代 ,也是人类生态意识开始觉醒的时代。增加绿色 ,是维护生态平衡唯一有效的生物工程。草坪是绿化中不可缺少的植物材料 ,他绿化速度快 ,效益明显。绿化没有草坪不行 ,没有草坪的绿地是一个不完整的绿地 ,当然只有草坪而没有乔木、常青树、灌木等也是一个不完整的绿地 ,只有乔、灌、草合理搭配 ,才能创造出植物景观丰富的园林绿地 ,才能达到园林绿化的目的 相似文献

随着社会的发展进步,城市园林化已成为趋势,大量的绿地出现在城市的各个角落。广场、游园、街头绿地、道路绿化等为城市增添了绿色,改善了城市环境,丰富了城市景观。相应地,绿地的增加使得绿地养护管理工作越来越繁重。应对这一现状,必须实现绿地的机械化养护管理,既使得绿地的养护管理工作逐渐由的人工作业向机械化、自动化转变,以便提高管理效率和养护管理水平。促进城市绿化事业的持续、健康发展。 相似文献

本文主要解析了我国城市园林规划设计的现状及存在问题,主要表现在总体规划忽视园林绿地设计师的参与,忽视植物空间布局与造景,破坏了原有自然景观和生态系统,缺乏地方风格与设计个性,人工植物群落设计简单,工程效果图与实际效果严重不符。指出我国城市园林绿化设计应遵循科学规划、注重细节,因地制宜、经济适用,以植物造景为主,以及以人为本,突出地方特色的原则。在此基础上,提出了我国城市园林绿化规划设计的对策与措施,强调城市总体规划与设计人员的参与,提倡以人为本,营造富于创造性的地方特色景观,加强设计人员与施工方的沟通,注重科研工作与人才培养,建立种质资源的种苗繁育与引种驯化,强化园林的施工与管理。 相似文献

In late December 1983, 2 800 veterinarians across Canada were sent a questionnaire in order to assess the status of heartworm disease in Canada in 1983 and 26% of them responded. Veterinarians reported that 59 504 dogs were blood-tested to check for microfilariae and 771 dogs (1.30% of those tested) were found with Dirofilaria immitis. Heartworm disease was diagnosed in all provinces except New Brunswick and Newfoundland but most (733) of the cases were in Ontario. Heartworm disease was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 31% of the cases were observed with clinical signs of heartworm disease and 64% had a history of not having left Canada. Southwestern Ontario continues to be the focus of the infection and most of the dogs there had not left the province previously. 相似文献

In late December 1985, 1485 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1985 and 44% of them responded. Veterinarians reported that 137,300 dogs were blood-tested to check for microfilariae and 1210 dogs were found with heartworm. Another 36 dogs were amicrofilaremic but diagnosed with heartworm disease to give the total number diagnosed in 1985 as 1247 (0.91%). Heartworm was reported from all provinces except Prince Edward Island, Newfoundland and Saskatchewan but most (1126) of the cases were in Ontario. Southwestern Ontario continued to be the primary focus of the infection in Canada. From Quebec, 91 cases were reported mostly from and around Montreal. From Manitoba, 19 cases were reported from Winnipeg and surrounding areas. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 28% of the cases were observed with clinical signs of heartworm disease and 78% had a history of not having left Canada. 相似文献

In late November 1989, 1732 clinics and institutional veterinarians were sent a questionnaire to assess the status of Dirofilaria immitis, and 51.7% responded. Of 247,716 dogs tested, 394 had D. immitis microfilariae and 51 were amicrofilaremic for a total of 445 cases and heartworm prevalence of 0.17%. Most (408) of these dogs had no preventive medication and the prevalence among dogs tested and unprotected was 1.01%. That prevalence was considerably higher in endemic areas. Thirty-seven dogs with heartworm had preventive medication. Heartworm was most frequent in companion dogs over three years of age maintained outdoors in rural areas. About 75% of the cases had never left Canada, 26% had clinical signs and 125 were not treated. Heartworm was reported from British Columbia, Manitoba, Ontario, Quebec, Nova Scotia and Newfoundland, but 383 cases were in Ontario. South-western Ontario was the primary focus of infection. There were 33 cases in Quebec and 24 in Manitoba, mainly found in and around Metropolitan Montreal and Winnipeg respectively. 相似文献
