Lawn green and pleasant, although to some extent, to beautify the urban environment, but the practice has proved that the development of a serious shortage of urban green lawn amount, do not form a reasonable pattern of green and three-dimensional space of the green network, but also to build lawn high cost, consumption Juicy and many other ills.
Some people think the uniform lawn, green, such as blankets, just like fashion style scenery abroad. However, from an ecological point of view, the rich diversity of visual experience is pleasant, which is like you are more willing to look at a variety of forests, rather than those monotonous neat large lawn. Secondly, it is easy to create the illusion of economic cost on. Same size lawns and forests, people often mistakenly think that the low cost of grass, trees and more costly, in fact quite the opposite. Moreover, consumption lawn too, the lack of biological diversity, the European countries almost no kind of it. Instant success but also the formation of a hot lawn important reason. Grass fast and effort, but planting is difficult, long cycle, slow, some officials in the pursuit of green achievements, the practical effect of excluding a large number of built lawn, causing great waste of financial resources.
From the global scope is concerned, this result with the target to improve the ecological environment is precisely the contrary. The application of scientific methods of urban greening step by step, to work as a manufacturing city greening "image projects", only to make green foam, no end of trouble. Ecological effect is the sole criterion for testing ecological means. From grass to bring our city in the wake of the bitter, the transition from grass keen to "retreat grass also tree", which should be a good sign.
China is now the most grass is more prescriptive requirements, such as how much square green area to reach what percentage, but kind of a nobody, that is, the tube is also very extensive tube. This does not comply with the law lawn growth. Today, many engine manufacturers began to make the transition lawn machinery, and localization mower will gradually occupied the domestic market, because its price is much lower than imported.
