The Institute of Sand Control of Gansu Province was established in 1980 on the basis of the Gansu Minqin Sand Control Comprehensive Experimental Station established by the Chinese Academy of Sciences in 1959. It is now affiliated to the Forestry Department of Gansu Province and is a provincial key research institute. For more than 50 years, the Institute has carried out comprehensive scientific investigations on the desert and Gobi of the Hexi Corridor around the needs of desert and desertification control in our province, carried out research on the development of sandstorm and aeolian landforms, and carried out geographical distribution of desert plants and germplasm resources. Protection and introduction and domestication of fine desert plants, the physiological and ecological characteristics of typical desert plants and their adaptation mechanisms to drought and wind erosion. The first set of near-surface sandstorm observation system was established in China, and three typical underlying mats were developed. Research on the temporal and spatial distribution of sandstorms in the surface (desert, desert-oasis transition zone, oasis); integration and research and development of land desertification and salinization control technologies, and establishment of desertification control models suitable for different regional characteristics, for ecological security in western China The sustainable development of social economy provides theoretical and technical support.
The Institute now has the State Key Laboratory of Desertification and Sandstorm Disaster Prevention (Cultivation Base) in Gansu Province, the National Field Scientific Research and Research Station of Gansu Minqin Desert Grassland Ecosystem, the Key Laboratory of Desertification Control in Gansu Province, and the National Position of Linze Desert Ecosystem in Gansu Province. Observatory Research Station, Minqin Shasheng Botanical Garden, Gansu Shasheng Plant Engineering Technology Research Center, Gansu Hexi Corridor Forest Ecosystem National Positioning Observation and Research Station 7 scientific research platforms; Gansu Minqin Sand Control Comprehensive Experimental Station, Jinta Zhisha Six field test stations including the test station, Linze Xiaoquanzi Sand Control Station, Jingtai Zhisha Test Station and Wuwei Oasis Station; the establishment of an international training center for desertification control, comprehensive desert management and sustainable agricultural countries to introduce foreign intellectual achievements Demonstration and promotion base, international scientific and technological cooperation base for desertification control and oasis sustainable development, national rural regional scientific and technological achievements transformation center, and national basic scientific talent training base, promote the popularization of desertification control technologies in China and the world, especially in the introduction and application of new technologies. The aspect played an important role.
Gansu Provincial Institute of Sand Control has 127 scientific and technical personnel, 20 research fellows, 42 associate researchers, 66 scientific research personnel and doctoral degree holders; 4 special allowances from the State Council; 8 leading talents in Gansu Province; There are 12 returnees studying abroad; 15 visiting research fellows, including 4 academicians; 16 masters and doctoral supervisors. A professional research team with distinctive characteristics and reasonable structure has been formed.
The institute has completed 416 scientific research projects, achieved 275 achievements, and won more than 80 scientific and technological awards, including 3 national awards and 40 provincial and ministerial awards; more than 2,000 papers published, 20 monographs published, and national patents. 54 items (including 7 invention patents); more than 30 items such as “National Advanced Forestry Science and Technology Unitâ€, “National Advanced Unit for Sand Control Technologyâ€, “Outstanding Contribution Award for National Ecological Construction†and “National Advanced Collective for Sand Control and Sand Control†Honorary title.
In 2016, the Gansu Sand Control Research Institute purchased 5 sets of surface runoff monitoring systems produced by Beijing Jiuzhou Space Science and Trade Co., Ltd., which have been installed and adjusted, and received favorable comments from users!!
Surface runoff monitoring system instruction manual
The surface runoff monitoring system is developed by the latest international CCD image sensor and Siemens infrared sensor. The community flow process observer adopts ARM technology, which has high reliability and strong stability. It is more cost-effective than the community flow process observer produced by the peers using 8-bit single-chip microcomputer and photoresistor!
[Principles of Surface Runoff Monitoring System]
It is mainly used for real-time online observation of soil and water conservation monitoring data of small-flow runoff communities in the case of natural rainfall or artificial simulated rainfall. In the same cell, according to the number of ports, the rainfall, runoff, sediment content, and soil erosion content of the runoff community with up to 18 ports can be provided at the same time. The automatic flow monitor of the production process in the community takes into account the inaccurate measurement accuracy of the peers in the R&D and production. The sensor part is transformed into a group of transmissions, three sets of receiving, and weighted evaluation algorithms, so that the observation of the flow generation process of our community The instrument has high acquisition accuracy. At the same time, the advanced 32-bit ARM technology makes the system run faster than the 8-bit 51 single-chip microcomputer used in the system, and the reliability is high.
[surface runoff monitoring system performance]
