浅谈城市园林绿化中的重要性

园林绿化是城市经济建设、精神文明建设和改善人民生活环境不可缺少的重要内容,是城市生态系统中最为活跃的生物多样性因素,城市园林绿化不仅具备环境效益,同时具有休闲娱乐、美学、生态和社会效益。从功效上看可以防止土壤侵蚀,滞尘、涵养水源并保持地下水不受污染,调节温度,减少声、光、视觉污染等,园林绿化可以使环境更加优美,更有吸引力,能促进人们身心健康,提高工作效率,缓解精神压力,充分体现城市活力和城市风貌。所以要在城市开展高标准园林绿化带,在近郊建森林公园、风景林、防护林、公益林,以此提高城市森林覆盖率。合理布置稳定的人工植物群落,是提高城市森林覆盖率的有效措施。要以高大的落叶乔木或常绿乔木为上木,以半耐荫的小乔木或常绿灌木为中木,水杉树苗批发广东快乐十分走势图以耐荫的小灌木作下木,由下木过渡到地被植物,这样就可以最大限度地发挥城市绿地的生态效益。

    目前园林绿化养护管理的现状养护管理在园林绿化建设中I一分重要,所谓“三分栽植,七分管理”,然而园林绿化的管理和养护依然是绿化行业的薄弱环节。具体表现在以卜几个方面:1对园林绿化工程养护管理工作缺乏足够的重视和认识。园林绿化工程养护管理工作需要投入大量的人力、财力、物力,很多施工单位在施工招投标时期都把免费养护两年,甚至三年作为一种优惠条件承诺与建设单位,所以造成很多园林绿化工程只是重建设而轻管理,苗木成活率低,养护管理不到位,导致绿化景观效果差而难以收到预期的效果。
