    December 21, 2018, the first edition of the China Science Daily published an article by journalist Yuan Yi xuece on "Neglected Macrobiology", which many biologists feel the same way, and has also attracted the attention of many ecologists. As an old ecological worker, the author also pays close attention to the current macrobiological research, so he also discusses the problems of macrobiology and ecology with researchers engaged in plant classification research and long-term scientific and technological workers working in the field ecological station.
    , the phenomenon of marginalization of macrobiological research has become internationalized, and there are not many researchers who really adhere to plant classification research in China.
    Institute of Applied Ecology (formerly the Forestry Soil Research Institute of the Chinese Academy of Sciences) of the Chinese Academy of Sciences is one of the four pillars of the Institute (forestry, soil, plants, microorganisms). In the mid-1960s, there were forty or fifty people in the plant room, who studied plant classification, moss, herchen, plant resource utilization, ground plants, and a specimen room. There are more than 20 plant classifications, and three survey teams go out to investigate each year. Liu Shenxuan, an old scientist, served as deputy director and director of the plant room, conducting classification and ground plant research.
    nearly two decades of declining plant rooms, old scientists have died and retired, and now there is only one person who really classifys plants. It is heartbreaking that the land plant and plant resource groups no longer exist.
    , the research of animal taxonomy in China is also short of talents.
    "marginalization" of macrobiology research, objectively 7th, due to changes in international macrobiology research trends. In the 1950s and 1970s, the rapid development of international molecular biology, in many developed countries, universities abolished the department of biology, this trend also affects the study of macrobiology in China. Many young people turn to microbiology. At the same time, China's relevant departments in policy, funding on macrobiology support is relatively small.
    , macrobiology research is difficult, often need to work in the field, trekking mountains and water, and dangerous. This kind of field working time is long, publishes papers, produces slow results. And in the laboratory to engage in micro-research, results, published papers quickly. As a result, fewer people sit on the cold bench.
    is the first resource, without reserve strength, macrobiology will naturally be less people. In this regard, engaged in plant classification research researcher Cao Wei said with deep feeling, the person engaged in classification is the master with apprentices, step by step brought out. From collecting specimens in the wild, understanding plants to indoor specimen identification, step by step, very slow and slow. A seed to be passed on, no seed can not be passed down. Plant classification is a classic, macro things are ignored, classics are ignored.
    Cao Wei also said that from the Northeast plant classification, there are about 3000 kinds of plants, the Northeast Biological Specimens Museum has 300,000 plant specimens. At present, at the county level statistics, there are many blank points, refined, there is still a lot of work to be done. The north-east plant history (including the north-east herb map and the north-east woody plant map) has been written for 50 years, including 12 volumes of herbs and one volume of wood. The first published part of many classification treatment can not reflect the current general classification treatment at home and abroad, restricting the development of plant resources survey and other basic work. Due to the lack of team and talent, revision is also difficult. The use of economic resources and plants also has a lot of work to do.
    , macrobiology is "marginalized" is a quick and quick approach. From my long-term experience of pollution ecology and regional ecological research, macro is the basis of micro, or micro-ecological research can not be separated from macro-investigation, and micro-is macro further in-depth.
    the late 1970s to the mid-1980s, our team carried out cadmium pollution prevention and control research in Zhangs pollution irrigation area of Shenyang. After determining that The Shenyang smelter is the source of cadmium pollution, and after the treatment meets the sewage discharge standard, the cadmium content of rice in the cadmium-contaminated area is still exceeding the standard, and some are still very serious.
    we found acid-emitting chemical companies along the drains through field surveys. At the same time, we also start from cadmium in the micro-acid meadow brown soil morphological analysis, to determine the form of cadmium mainly acid-soluble state. With the increase of soil acidity, cadmium dissolves in soil and causes the absorption of cadmium by rice to increase. Therefore, we take cadmium control, acid control, increase soil pH, serious pollution areas to plant seedlings and other ways to prevent and control cadmium pollution, and achieved good results.
    the end of the 1980s, the local government changed the cadmium-contaminated area into an industrial-oriented economic and technological development zone, thus ending the cadmium prevention and control research in the cadmium-contaminated area. Through cadmium pollution control, it is shown that the ecological research of pollution needs to be combined with macro-investigation and micro-research in order to achieve better results.
    is an important part of biology and is closely related to industry, agriculture, economy and social development. It provides theoretical basis and practical application to solve the problems of population, food, environment, resource security and so on. It provides a scientific basis for major national decision-making from a biological point of view.
    in the 1950s and 1960s, Liu Shenxuan and other older scientists worked to make the Baolan Railway successfully built and opened to traffic, which is a perfect example of the combination of macrobiology and ecology. Of course, desertification control is now also using microbiological research, that is, the use of microbial-induced calcium carbonate precipitation method to solidify loose sand and soil together, so that sand control has made progress, but still need to be based on macrobiological investigation.
    , a researcher at the Shenyang Institute of Applied Ecology, is the director of hunan's co-ed field ecological station, which has now become a national field science observation and research station for forest ecosystems. He worked with the workstation for more than 20 years. He believes that from the perspective of macrobiology and ecology, economic plants need to be further explored and developed, and the construction of ecological civilization and ecological security of the country also need to be scientific research from the perspective of macrobiology and ecology.
    , Hunan will be a biodiversity reserve and a water conservation area of Dongting Lake. To protect the forest area is to protect the safety of the people and living things of Dongting Lake. An important research topic at the same station now is how to help local economies develop, which requires a combination of local industrial development and the conservation and use of forest resources. This also requires the study of forest resource development from a macrobiological perspective. But at present, a lot of resources are not clear, this first needs to know the plant people to carry out field research. This is just one example.
    China is a vast country, many biological resources, including plants, animals, microorganisms and fungi, need to be further investigated and identified, developed and utilized, for economic, social development and population health services. China's macrobiology research has a long way to go.
