The Institute of Global Environmental Change (IGEC) was set up in 2010. Distinguished Professors of Dr. Cheng Hai and Dr. Huang Shaopeng have built associated research teams.

Based on the research advantages and foundations of engineering and multidisciplinary resources of Xi'an Jiaotong University, the orientation of the IGEC is to generate systematic research features of 'Greenhouse gas‒Climate change‒Energy saving‒Human settlement‒Adaptation strategy', which means to use the Open‒United Mode to force the IGEC’s original scientific innovation. To establish paleoclimate sequences in the low and middle latitudes on different timescales on the basis of advanced isotope tracer technique and geochronology laboratory (AMS‒14C and MC‒ICPMS‒Uranium series) for the studies of the rule and mechanism of the Asian monsoon and the Westerly belt climate under global framework. Meanwhile, to enhance the relationship studies between subsurface temperatures and global warming, as well as the aerosol emissions, to quantitatively track the mission of greenhouse gas using high-tech approaches, to develop the key technologies of greenhouse gas emission reduction and energy sustainable utilization. The goal of the institute is to create technological approaches for the fitness of human settlements to global change, and accordingly to serve the Chinese environmental diplomacy, the eco-environmental improvement, and the sustainable development of economic society.


1. Isotope Laboratory

(1) Overview

The Isotope Laboratory, founded by Prof. Cheng Hai in 2010, aiming to provide fundamental and technical support for frontier scientific research of global environmental change.

(2) Facility

The lab consists of U-series Chronology Dating Laboratory and Stable Isotope Laboratory. The U-series Chronology Dating Laboratory is equipped with ultra-clean laboratory, including 10,000‒Degree ultra-clean instrument laboratory, 1000‒Degree ultra-clean chemical laboratory, and ten 100‒Degree ultra-clean safety cabinets with different sizes. The laboratory can be monitored and controlled by an external computer to ensure the experimental conditions of constant temperature and humidity in the clean room to meet the chemical treatment requirements of the samples and to provide a stable external environmental condition for the normal operation of the Plasma Sourced Multi-collector Mass Spectrometry (MC-ICP-MS). The ultra-clean environment is regulated by a multi-stage filtered ventilation system that enables real-time and remote control operations. The laboratory has completed a large number of chemical treatments and instrument analysis works.

The Stable Isotope Laboratory has Stable Isotope Mass Spectrometry MAT-253, MAT-253 Plus, and Delta V Plus, as well as two Kiel-IV micro-carbonate device that can capture abundant high-resolution and high-precision stable carbon and oxygen isotope within a short time, and also can use for the measurements of triple isotope composition. The Picarro L2140-i, a Water Isotope Analyzer, can be used to measure meteoric water, Karst precipitation, karst drip, and atmospheric vapor. The laboratory is also equipped with a Zeiss fluorescence, a polarizing microscope, a Laser-Induced Breakdown Spectroscopy (LIBS), a diamond wire cutting machine, and a Micromill micro sampling device.

2. Geothermal and Environmental Research Laboratory

(1) Overview

The Geothermal and Environmental Research Laboratory (GERL) has three branches, a thermophysical lab, a thermal environmental and meteorological observatory, and a numerical platform. The GERL is a subsidiary of the Institute of Global Environment Change and the School of Human Settlements and Civil Engineering. The strength of the GERL is enhanced through its close collaboration with the State Key Laboratory of Multiphase Flow in Power Engineering, the Ministry of Education Key Laboratory of Thermo-Fluid Science and Engineering, and the School of Energy and Power Engineering of the Xi’an Jiaotong University. The major research interests of the GERL include terrestrial heat flow and crustal thermal structure, geothermal resource exploration and utilization, Earth radiation budget experiment on the Moon, land-atmosphere thermal interaction, and underground urban heat island effects.

(2) Facility

The GERL is equipped with several advanced thermophysical property meters of Netzsch, Lippmann, Isomet, and Xiaxi brands; high precision well logging systems capable of measuring subsurface temperature up to 350 °C in a supper deep borehole down to 6 km; multiple sets of magnetotellurics (MT) sounding systems; and a unique thermal and meteorological observatory comprised of a standard ground based meteorological station, two rooftop meteorological masts, four 5-m soil temperature/moisture probes, and a 500-m deep observation borehole. Moreover, the GERL has an array of personal computers, high-speed workstations, and an interdisciplinary geothermal environmental database to support its research activities.

3. Water Resource and Environment Laboratory
