| 英文简介 | Shrub of h. ammodendron windbreak and sand-fixation, ecological restoration, h. ammodendron trees in recent years, h. ammodendron parasitism in the host, big non-success is to increase income, improve the ecological and control the development trend of the desert. H. ammodendron tree planting density and irrigation water is unreasonable, the survival rate of h. ammodendron decreases, resulting in a decline in the production of the parasite, due to the wind tree of h. ammodendron planted rows planting distance affect its illumination time, survival rate, windbreak and sand-fixation effect. For free access to the forest, gradually reduce the wind speed, wind gradually hold the migration of particles of different height, every tree to study and put forward the main h. ammodendron in place are independent of each other, each other is not diamond plant form of keep out sunshine, at the same time, the diamond wind invade the edge density of planting different intercropping vice, diamond internal rules of the host plant host etc. Simulated experiments, all kinds of the experimental results were analyzed to host more forest vertical diamond level plant model. The project to field experiment research, the model and simulation experiment and field experiment of contrast optimization effect of windbreak and sand-fixation plant mode, in this mode to establish the forecast model of wind velocity attenuation and sand-fixation rate. According to the law of changes in soil moisture and climate, we determine the mode of comprehensive irrigation under different irrigation water quota, correct quantitative water saving effect, and degree of control the spread of desertification. For improving the windbreak and sand-fixation, restoration ecology, provided in accordance with the economic and social benefits。 |
