The oyster reef component based on the intertidal photovoltaic pile foundation and the manufacturing method thereof can not only provide a suitable habitat for oysters, but also can repair the intertidal habitat of a photovoltaic field area, increase the types and density of benthic organisms, and restore the biodiversity of the photovoltaic field area.

This invention discloses the use of phytic acid in the preparation of drugs or functional foods for regulating intestinal flora imbalance caused by Streptococcus mutans, belonging to the field of biomedicine and microecological regulation technology. This invention is the first to discover that oral phytic acid can effectively inhibit the abnormal colonization of Streptococcus mutans in the intestine, restore intestinal flora diversity, increase the abundance of beneficial bacteria (such as Bifidobacterium and Lactobacillus), reduce the proportion of pro-inflammatory bacteria, and improve intestinal barrier function and inflammatory status. This invention provides a new strategy for regulating intestinal flora imbalance caused by Streptococcus mutans.

The invention discloses a grassland area strip mine vegetation recovery method, and relates to the technical field of mining area vegetation recovery, and the method comprises the following steps: clearing and leveling a recovered land parcel: removing sundries, dead wood and weeds on the land parcel, and digging out broken stones on the earth surface and large stones buried in soil for clearing; according to the method, grass such as wheatgrass, elymus dahuricus, sweet clover and puccinellia angulata and shrubs such as cornus swida, Gansu berberis thunbergii, buxus sinica and alhagi sparsifolia are planted in a mixed mode, the grass or the shrubs are developed in root system, high in vitality and extremely high in adaptability to the environment, soil is gradually compacted under the action of vegetation root systems and is not prone to loss, meanwhile, vegetation is spread all over the ground, and the soil is not prone to damage. The land surface environment is improved, the probability of sand storm occurrence is reduced, grassland pasture gradually recovers along with continuous growth of vegetation, the quality and yield of grassland pasture gradually increase, and the biodiversity of plant communities gradually recovers, so that the service function of a grassland ecosystem gradually recovers, and the grassland ecosystem can work normally.
