Recently, China Forestry Press held a symposium on the theory and technology of grassland ecological restoration and a new book launch of "Main Technical Models of Ecological Restoration of Degraded Grassland".

Recently, China Forestry Press held a symposium on the theory and technology of grassland ecological restoration and a new book launch conference for "Main Technical Models of Ecological Restoration of Degraded Grassland". The book was commissioned by National Forestry and Grassland Administration Beijing Forestry University Dean of the School of Grassland and Grassland Professor Dong Shikui As the person in charge, he organized more than 60 experts and scholars in the field of grassland ecological restoration research across the country to carry out ecological restoration of degraded grasslands. The special study on technical models was compiled based on 2 years of systematic research work.

"Main Technical Models for Ecological Restoration of Degraded Grassland" new book launch conference

The book is edited by Professor Dong Shikui, and more than 60 experts and scholars in the field of grassland ecological restoration across the country serve as editorial board members. Academician of the Chinese Academy of Engineering Ren Jizhou, and Tang Fanglin, Director of the Grassland Management Department of the National Forestry and Grassland Administration respectively wrote prefaces and spoke highly of them: " The first good book on scientific grassland restoration work " "From the perspective of technical points, management models, It provides a comprehensive introduction to each ecological restoration model from multiple dimensions such as effectiveness evaluation and suitable promotion scope."

Professor Dong Shikui

"Main Technical Models for Ecological Restoration of Degraded Grassland" is comprehensive and systematic in content. covers for the first time the degradation restoration models of all types of grasslands in different regions from north to south and from east to west in my country. .

• systematically introduces the technical model of ecological restoration of degraded grassland in an all-round way from the causes, degradation status, and degradation types of grassland to the technical selection, management model, effectiveness evaluation, promotion area and other ecological restoration factors of ecological restoration;
• starts from the design, The entire process of construction, management, evaluation, etc. introduces each ecological restoration case in detail. fills the gap in grassland book publishing in this regard. ;
• integrates the theoretical and practical foundation of the writing team that has been engaged in grassland ecological restoration for many years, forming "zoning, classification, and grading." "Technical model for ecological restoration of degraded grassland.

These models are representative results that are scientifically advanced, mature, effective, highly targeted, and highly practical. They have the characteristics of being popularized, replicable, and applicable, and can serve as a useful resource for forestry and grassland science and technology and management workers, technology extension personnel, Audiences such as teachers and students in colleges and universities and farmers and herdsmen can learn from it and scientifically guide and promote the ecological restoration of degraded grasslands.

Grassland is an important ecosystem and natural resource in my country, and the restoration of degraded grassland is related to national ecological security. In recent years, Professor Dong Shikui's team from the School of Grassland and Grassland of Beijing Forestry University has continued to delve into the theoretical and technical problems of ecological restoration of degraded alpine grassland on the Tibetan Plateau, and has achieved a series of important results and progress -

• proposed the "grassland degradation " From the perspective of "the comprehensive effect of internal and external factors", has improved the theoretical system of alpine grassland degradation ;
• has constructed an alpine grassland vegetation degradation index based on indicators such as grassland vegetation coverage, biomass, height, and proportion of dominant plants in the climax community ( GDI), supplements the shortcomings of the existing alpine grassland vegetation degradation evaluation system ;

In 2022, the scientific research team of the College of Grassland and Grassland made a series of progress in the functional mechanism of typical grassland mycorrhizal networks

• clarified the vegetation-soil of alpine grassland degradation Interface ecological processes and effects , found that grassland degradation reduced plant diversity and soil animals, microorganisms biodiversity and changed grassland plant, animal and microbial community composition;
• proposed the "zoning, classification, classification, Based on the "graded" ecological restoration technology model, has developed artificial grassland restoration technology for extremely degraded grassland ("black soil beach" or "rat wasteland") based on "design theory", and has screened out practical methods suitable for the restoration of extremely degraded grassland. Perennial grasses (Elymus macula, multi-leaf old wheat, grassland bluegrass , etc.), compared and selected the best mixed sowing community design of different grasses, and proposed to maintain the stability of the perennial grass mixed sowing community. Fertilization, grazing and mowing control technology.

...

These research results are mainly published in domestic and foreign high-level journals such as BioScience and Global Environment Change, including more than 50 SCI journals papers and more than 20 Chinese core journal papers.

At the same time, the Beilin Grassland and Grassland College team published 4 monographs in well-known domestic and foreign publishing houses such as Springer and Science Press , and won the first prize of the Science and Technology Progress Award of the Ministry of Education, and the first and second prize of the Tibet Autonomous Region Science and Technology Award. 1 each, 1 first prize of Qinghai Province Science and Technology Progress Award; provided 4 consulting suggestions to departments at all levels, for the ecological environment construction of the Qinghai-Tibet Plateau (especially the ecological environment construction of Sanjiangyuan), sustainable management of grassland resources and It provides scientific and technological support for the effective solution of ecological environment and livelihood issues for farmers and herdsmen to get rid of poverty and become rich, which is important for curbing the continued deterioration of the grassland ecological environment in the Qinghai-Tibet Plateau, restoring degraded grassland ecosystems, improving the ecological functions and production levels of grassland, and maintaining the Qinghai-Tibet Plateau and The ecological security of the middle and lower reaches plays an important role and significance.

In 2021, the national key research and development plan "Research on the Diversity and Ecological Functions of Non-symbiotic Nitrogen-fixing Microorganisms in Alpine Grassland Soil" led by Professor Dong Shikui was launched.

"The lifeblood of people is in the fields, the lifeblood of the fields is in the water, the lifeblood of the water is in the mountains, and the lifeblood of the mountains is The lifeblood of the soil is the lifeblood of the forest and the grass. After years of hard work, Beilin grass scholars have submitted the " Beilin Answer Sheet" with their research and hard work to protect my country's ecological security. In the future, the college will continue to closely focus on the idea of ​​"systematic management of mountains, rivers, forests, fields, lakes and grasses" proposed by the 19th National Congress of the Communist Party of China, insist on promoting the output of original results, and build an internationally renowned, domestically first-class, high-level, distinctive university. Open, innovative grass industry and grassland college!

This September, let’s meet at Beijing Forestry University and start a “green” journey together!
