地面覆盖即通过一定的栽培技术措施,使生长的植物在地表上山其叶片形成一个覆盖层,这个覆盖层要保持一定的密度和厚度,防止其它植物(例如野草)的生长。由于缺少阳光,使野草不能正常生长,这种情况在自然界是时常可以见到的,即“适者生存,优胜劣淘”。在花园中所不同的是,这种选择生存植物的不是环境,而是园艺工作者。个花园就是一个人造的小气候环境,在英国诸花园内,几乎所有的植物都引种于其他气候条件或近乎英国自然条件下不能正常繁殖的树种,在花园中所 The ground cover means that through the cultivation measures, the growing plants form a cover on the surface of the mountain. The cover must maintain a certain density and thickness to prevent the growth of other plants (such as weeds). Due to the lack of sunlight, the weeds can not grow normally. This situation can often be seen in nature, that is, “the survival of the fittest is superior and inferior.” What is different in the garden is that the plant chosen to survive is not the environment but the horticultural worker. A garden is a man-made microclimate where almost all the plants in the English gardens are introduced to other climatic conditions or species that can not normally reproduce under the natural conditions of the United Kingdom,
