以北京市大兴区平原造林为例,将大兴区平原造林分为生态涵养主导型、景观游憩主导型和生态廊道型3个类型。通过实地调研、查阅数据、专家咨询、技术分析等方法进行分析比较和研究,提出以下改造提升对策:生态涵养型主导型地块,通过抚育间伐、树种更替、建立保育区等措施,向培育近自然复层异龄林目标努力;景观游憩主导型地块,在发挥森林资源生态效益的基础上,打造精品绿地,增加道路、景观节点等景观空间结构;生态廊道型地块,完善主要道路、河流两侧的绿色生态廊道,注重连通生境孤岛,为小动物创造生境和迁徙条件。

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.
