用自然植物景观建绿色森林城市 　　摘要城市森林是城市范围内及与城市关系密切的、以树木为主体的生物群落。建绿色森林城市是通过城市森林植物造景，应用乔木、灌木、草本以及藤本植物来创造景观，充分发挥植物本身形体、线条、色彩等自然美，配植成一幅幅美丽动人的画面，供人们观赏。大连市的植物造景结合地形、水体、道路来组织植物景观。按照森林城市建设目标，到2010年，大连市有林面积将达到810万亩，森林覆盖率由现在的41.5%提高到45%，基本建成比较完备的林业生态体系。到2020年，大连市将实现荒山全部绿化，形成有水皆清，森林围城，城在林中的人与自然和谐共处格局，生态环境将达到世界发达国家水平。目前，城市森林建设总体规划已被纳入大连市“十一五”规划，成为推动大连林业生态建设核心内容。 　　关键词 植物景观;绿色;森林城市 　　Abstract: The urban forest is the biological communities regarding the trees as the main part within and close to the city.
