At the same time, can the ice and snow and birds singing and flowers blooming together, and can the desert Gobi and wetland oasis coexist? In China, the answer is yes. Our country has a vast territory and is both land and sea, and its complex natural ecosystem has nurtured rich biodiversity . In order to improve the self-repair ability of ecosystems, my country has clarified the overall layout of major national ecosystem protection and restoration projects with the "three zones and four belts" as the core. Northeast Forest Belt is the only forest ecological barrier belt of and .

In recent years, Beijing Forestry University Forest Management Huang Danian-style teacher team has built internationally leading field research platform, published more than 40 academic papers with important international influence, and made significant research progress in the field of Northeast Forest Biology Diversity and productivity research. This issue is pushed, let us go and find out!
Due to over-deforests and unreasonable utilization in history, the proportion of primitive forests in Northeast China's forests accounts for less than 7%, and there are prominent problems such as 's single structure and continuous decline in ecosystem functions ; and Northeast natural forests are the main body of my country's natural forests. Improving forest quality, restoring ecosystem functions, improving biodiversity, and promoting forest "carbon sequestration and increase sinks" have become the core tasks of implementing the national strategy for natural forest protection and restoration.
With the support of the National "13th Five-Year Plan" typical fragile ecological restoration and protection research key project - Northeast Degraded Forest Ecosystem Restoration and Reconstruction (2017YFC0504000) project, Beijing Forestry University National College Forestry University Huang Danian-style Teacher Team and other coordinated organization related units in the area to coordinate and organize relevant units in the area. We systematically built a long-term positioning research platform for the Northeast forest based on the combination of large-area monitoring sample sites and geographic grid sample sites. The total area of large-area sampling sites is 350ha, and positioning observations are carried out on more than 1.8 million trees; there are 510 geographical grid samples, 900 shrub sample samples, more than 1,350 herb sample samples, 83,000 annual rods were obtained, 50,000 plant trait samples, and 1,800 soil samples. Based on detailed point-to-surface combined with platform big data, the
team carried out research around key areas such as biodiversity and ecosystem functions, and achieved a series of research progress in 's landmark and leading , and published more than 40 high-level academic papers, including 28 TOP journal papers , with a cumulative impact factor of 209.79. Related results are published in Global Change Biology, Global Ecology and Biogeography and other Forestry or ecology top international academic journal .
Research results achieved by this team was promoted by National Forestry and Grassland Administration in the national natural forest areas . Beilin The results of the "Northeast Secondary Forest Multi-target Management Theory and Key Technologies" led by Professor Zhao Xiuhai will be promoted and applied as the main technical measures for the implementation of the " Natural Forest Protection and Restoration System Plan ", and will be included in the "National Medium- and Long-term Plan for Natural Forest Protection and Restoration" , becoming an important scientific and technological basis for promoting the high-quality development of national natural forests.

In the field of biodiversity maintenance mechanism , the Beilin team clarified the latitude gradient pattern of β diversity in Northeast forests; revealed the mechanism of influence of environmental filtration on the functional composition of temperate forests; created a new method to quantify community composition differences ; based on long-term monitoring data of sample sites, the impact of biological and abiotic factors on the growth and survival of trees throughout the life history stage was explored. Related results are published in journals such as Frontiers in Plant Science.
In the field of biodiversity and ecosystem function research , the team clarified the scale dependence of the relationship between biodiversity and productivity; revealed the distribution pattern of forest vegetation carbon storage in Northeast Asia , and reported for the first time in Northeast China forest carbon storage; constructed a single-wood growth model of the major tree species in Northeast China and analyzed the factors that affect their growth; based on long-term positioning observation, an appropriate logging intensity to improve forest carbon storage was established. Related results were published in journals such as Journal of Ecology.

From dense forests to neat data, each achievement contains the efforts of the Beilin team for several years. The forest management teacher team was selected into the first batch of "National College Huang Danian-style Teacher Team" of the Ministry of Education in 2018, and has now become the top research team in the field of international forestry. The international cooperation results of the team's teachers' participation were once on the Nature cover , and the story of teachers and students "going out of business" was once published in Guangming Daily .
In 2019, Nature magazine published the research results "Climatic controls of decomposition drive the global biogeography of forest-tree symboloses" in the form of a cover article. Professors Zhao Xiuhai and Professor Zhang Chunyu participated in the research, and Beijing Forestry University is the fourth author unit of the paper.
2021, " Guangming Daily " published "Scholars who "grow" on trees - Young Forest Learning in the Mountains and Forests", which tells the story of young forest students in the Beilin Forest Management Teacher Team.
Teaching in the classroom and educating people in the mountains and forests. Beijing Forestry University team runs through the vast forest day after day. Under their watch and inheritance, the spirit of Beilin is endless, and the students of Beilin are also as solid and steady as trees and are growing slowly.
