Taking the plain afforestation in Daxing District of Beijing as an example,the plain afforestation is divided into three types: ecological conservation leading type,landscape recreation leading type and ecological corridor type.Through field research,data access,expert consultation,technical analysis and other methods for analysis,comparison and research,the following promotion strategies were proposed : For ecological conservation leading plots,strive to cultivate the goal of near natural forest through measures such as tending thinning,tree species replacement and establishment of conservation area;On the basis of giving full play to the ecological benefits of forest resources,the landscape and recreation leading plots need to build high-quality green spaces and add landscape spatial structure design such as roads and landscape nodes;For ecological corridor plots,improve the green ecological corridors on both sides of main roads and rivers in plain areas,pay attention to connecting habitat islands,and create habitat and migration conditions for small animals.
