The second International Symposium on the geo-ecological survey of the global black soil critical zone successfully concluded in Harbin

The 2nd International Symposium on Global Black soil Critical Zone Geo-ecological Survey(BASGES) and the Annual Summary Meeting of IGCP-665 Work Project were successfully held in Harbin. The scientific problems of Global Black soil Critical Zone Geo-ecological Survey were discussed in depth. The work of IGCP in the past year was summarized, and the work deployment for the next year was arranged. The next step is clear.
At the meeting, Li Zhizhong, director of Shenyang Geological Survey, China Geological Survey, Ministry of Natural Resources of the People’s Republic of China, welcomed the arrival of experts from all over the world. He stressed that black soil is the most precious soil resource in the world. There are only four black soil regions in the world. They are all important food producing areas in their countries and have an important impact on global climate change. In the future, we should carry out the geo-ecological survey of the global black soil critical zone by the "3M" method of the earth critical zone, through IGCP project organization and implementation, strengthen cooperation to achieve a new breakthrough in black land investigation and research.

Li Zhizhong, director of Shenyang Geological Survey, delivered a welcome speech
Cheng Qiuming, President of the International Federation of Geosciences, and Peng Suping, academician of the Chinese Academy of Engineering, were invited to attend the meeting. They made brilliant speeches on the significance and future development of geo-ecological survey in the black soil critical zone, respectively. At the same time, he highly affirmed the current achievements. At the meeting, the Black soil Research Center of the China Geological Survey was unveiled and established. On behalf of the research center, Director Li Zhizhong hired Academician Peng Suping as the director of the Academic Committee and Chairman Cheng Qiuming as the director of the Advisory Committee and issued the letter of appointment.

During the meeting, Dr. Wang Daming reported and summarized many important progress made since IGCP-665 project was approved.
1. China – Czech project
In July 2018, we applied for the China-Czech Regular Scientific and Technological Meeting Exchange Project, named "Orbiting Satellite Soil Mapping and Monitoring". The main content of cooperation is that the two sides jointly carry out research work on soil quality information inversion, mapping and monitoring based on orbital satellite data.
2. CGS project
Continue integrated geological survey in Northeast China in 2018. At present, 44 960 square kilometers of 1:250,000 geochemical survey, 100,000 square kilometers of satellite remote sensing survey and 1500 square kilometers of aerial hyperspectral survey have been completed.
The International Blackland Association has signed letters of intent for cooperation with several national research organizations. At present, seven research organizations have signed letters of intent for cooperation, and four research organizations are signing letters of intent.
4. INBS collaboration
Attended the international symposium on black soils,Attended the 1st workshop of INBS,Project collaboration with Heilongjiang Academy of Agricultural Sciences.
5. IBSS/IGCP665 website
Set up the /IGCP665 website of the international black earth Association.
6. Social activities in Northeast China
By using the results of land quality geochemical survey of our center, we have planned and built a natural green selenium-enriched rice demonstration base in Changfa Town, and successfully built the reputation of “Longjiang Selenium First Village”. In 2017, Changhua Village sold 83 tons of natural selenium-enriched rice, which was higher than the market price of 3.6 yuan/kg.

We have also constructed a demonstration farmland for selenium-enriched rice planting in Dongliao County, and a traceability management system for the geo-ecological environment of the northeast specialty agricultural products. The origin of agricultural products can be obtained through a QR code on the product packaging, through which consumers can inquire about agricultural soil types, soil organic matter, nutrients, beneficial elements and heavy metal pollution information services.
7. Background data collection and atlas
We collected data from Geochemical and Mineralogical Surveys by USGS, Multi-purpose Geochemical Surveys by SGS, GEMAS by EuroGeoSurvey, WEGS, FOREGS. We also collected remote sensing survey data from Land Remote Sensing Program by USGS, World Soil Spectrum Lib by CSIRO and Space-Air-Ground RS Survey by SGS.
An atlas has been mapped based on these background data. The Atlas is divided into three scales: global scale (46°N black soil area), regional scale, local scale. The contents include Ecological related maps of soil types, land use changes, surface vegetation cover, and carbon emissions in the global black soil region, Ecologically relevant maps such as regional scale temperature, primary productivity, and precipitation, Ecological related maps of Sanjiang Plain, Helen, Baoqing, and Qixing Farm.
8. BASGES / IGCP 665 research plan
The IGCP research plan has been formulated. The IGCp research program includes eight aspects.
 Multi-scale remote sensing survey and monitoring
 Spectral survey
 Multi-scale geochemical survey
 CZOs construction and comparative study
 comprehensive modeling of Key Belt
 Carbon cycle research
 Microbial research (under preparation)
 Construction of sharing platform including data, models, information and other applications sharing platform
Experts from the United States, Russia, Czech and the United Kingdom participated in the meeting, and conducted in-depth exchanges and discussions on eight research directions of remote sensing application, geochemical application and sharing platform construction in geological and ecological survey of black soil critical zones.
