Shrubrication (Shrub encroachment) refers to a globalization phenomenon characterized primarily by an increase in coverage, density and biomass of woody vegetation.
Impact of grassland shrubation on biodiversity: on the community scale, shrub expansion can change the aboveground and underground biomass, the amount of the withered matters and the biodiversity of the vegetation of the ecological system. As shrubs expand, plant species abundance in 13 ecosystems decreases significantly.
Effect of grassland shrubation on grassland productivity: the crowns of the bushes limit the utilization of the lighting and moisture resources by the herbs, and the shrubrication significantly reduces the grassland productivity. The productivity of herbs is reduced. While extreme changes in light environment will help the bushes exclude potential competitors during establishment and rapidly change community structure and ecosystem function. Different degrees of shrubrication can also produce different influences on grassland productivity, the coverage of shrubs in light shrubrication is not large, the illumination level under the forest is moderate, and herbaceous plants show higher utilization efficiency on soil surface layer nutrients, so that the grasslands are beneficial to growth, but the shrubs vegetation in heavy shrubrication grasslands are relatively dense, light rays can be intercepted, and the retaining effect on soil nutrients and moisture is weak, so that the productivity of herbaceous plants is reduced.
After the grasslands are shrunken, woody plants replace herbaceous plants, the productivity of the grasslands is reduced, and how to control the further aggravation of the grassland shrunken becomes a current research hot spot. The device is more urgent in that the device can timely monitor the structure of the grassland shrubs, the device needs to be moved to a sampling area, then sampling is carried out on a sampling side (about 5 x 5m or 10 x 10 m), the coverage of shrubs in the sampling side, the height and the identified dominant community type are measured, finally, the device can also monitor the individual level in the sampling area, so that the related data such as the height, crown width, leaf area and identified type of the grassland shrubs can be quickly obtained, the population of the grassland shrubs is analyzed, and measures are timely taken to reduce or stop the shrubs, and the grassland productivity is improved.
