A saline-alkali-resistant and windproof landscape forest in the coastal areas of South China

Abstract

The invention relates to a saline-alkaline tolerance windproof landscape forest in coastal regions of the southern part of China. The windproof landscape forest comprises four parts, namely a first scattering structure shrub and herbaceous plant zone, a second air permeation structure tree frost zone, a third scattering structure tree and bush zone and a fourth air prevention tight structure tree,bush and grass zone which are constructed from 400-800m away from a flood tide water level from a coastal zone to a land in sequence. With the mixed combination of scattering structures, air permeation structures and tight structures, a single structure of a conventional wind prevention forest is changed, a typhoon running route has complex resistance, due to the air scattering and permeation structure at the front end, typhoon can be scattered and led to high spaces with less buildings and human activities, wind near the ground is further dredged by the scattering structures and is finally baffled by the tight structures, then production and living activities in the windproof forest can be protected, and typhoon loss can be reduced. The windproof structure provided by the invention is reasonable and good in windproof effect.

Description

Technical field[0001]The invention belongs to the field of agriculture and forestry, belongs to the construction technology of windbreak forest, and particularly relates to a salt-alkali-tolerant windbreak landscape forest based on native plants in coastal areas of South China.Background technique[0002]With an average of 7 typhoons landed every year, my country has become one of the countries with serious typhoon disasters in the world. Especially the economically developed areas in my country represented by the Pearl River Delta-the coastal areas of South my country are the areas most severely and frequently affected by typhoons in China. According to statistics, in 2017, Typhoon Hato caused 468,000 people in Guangdong Province to be affected, with a direct economic loss of 11.92 billion yuan, and a direct economic loss of 260 million in Fujian, Guangxi, Guizhou and other provinces. In 2018, although governments at all levels took early preventive measures, However, typhoon Mangkhu...

Problems solved by technology

Green forests are often used instead of windbreaks around the real estate and industrial parks, and a large number of exotic plants are introduced during the construction process, which is not only costly but also unable to adapt to the soil salinization environment in coastal areas, and cannot play the role of windbreak

However, the original windbreak forest model cannot provide ornamental functions for various production centers and industrial parks
