Professor Du Rulin, in 1987 was named an advanced individual in the scientific and technological front of Hebei Province. In 1991, he was appraised as "advanced science and technology worker" by Hebei Provincial Education Committee. In 1990 and 1991, he was recommended by the United Kingdom and the United States as a world achievement figure. Approved to enjoy special government allowances in 1992. In 1995 won the title of outstanding expert in Hebei Province. In 2001, he won the 7th Li Siguang Geological Science Award.

Professor Du Rulin was the 35th member of the Chinese Geological Society.

The "Precambrian paleontology and geohistory" written by Professor Du Rulin is the first textbook that systematically discusses Precambrian paleontology and geohistory in China and the world. He has repeatedly been awarded the Academy's Advanced Teacher and Excellent Teaching Quality Award. He was awarded the title of Model Worker in Zhangjiakou City in 1985, and was awarded the National Excellent Teacher Award in 1993.

Professor Du Rulin has long been engaged in scientific research on precambrian strata and paleontology, and has done a lot of systematic and pioneering work. He has undertaken many national and ministerial major basic projects, national natural science foundation projects, and international cooperation projects, and has won national, provincial, and ministerial awards. It is recognized as one of the academic leaders in the fields of the Middle and Upper Proterozoic, macro algae and stromatolites in China. He has published more than 60 papers and 5 monographs at home and abroad. He was invited to Australia and Canada for cooperative research and academic exchanges.

In the study of pre-Cambrian stratigraphy in North China in the 1960s and 1970s, he discovered and named the Wutaishan Iron Fort movement, established the Upper Precambrian stratigraphic sequence in the western Yanshan section, and divided and stacked the Xiamaling Formation The discovery of the stone and the establishment of the Zhaojiazhuang Formation in the Taihang Mountains were highly praised and evaluated by domestic experts. They collectively won the third prize of the National Natural Science Award, and the Ministry of Geology and Minerals also issued a commendation order for this.

The spiral macrofossils he and Tian Lifu discovered in the Gaochengzhuang Formation of the Jixian Great Wall in Tianjin are the oldest known macrofossils, filling the gap in China and Asia in the absence of such fossils, which is a major breakthrough. This achievement won the first prize of scientific and technological progress in Hebei Province in 1992. The earliest macroalgal fossils with organ differentiation and benthic origin were found in the Changlongshan period of Qingbaikou system in Huailai, Hebei and other places, named Longfengshan algae. This project was approved by the National Science and Technology Commission as a major national scientific and technological achievement. The above two achievements and other cooperation achievements won the second prize of the 1995 Science and Technology Progress Award of the Ministry of Geology and Mining. It was also designated as one of the 13 major exhibiting projects of the Ministry of Geology and Mineral Resources at the 30th International Geological Congress.

He has also made a breakthrough in the research of the National Natural Science Foundation of China "Biological mineralization of the Xuanlong iron ore in the Great Wall of Northwest Hebei". A large number of micro-paleophyte fossils were discovered for the first time in the ancient iron ore of nearly 17-1.8 billion years, which changed the traditional view of biological mineralization and provided a typical example for the research of biological mineralization of iron ore in China. In 1994, he won the second prize of scientific and technological progress in Hebei Province.

Professor Du Rulin, in 1987 was named an advanced individual in the scientific and technological front of Hebei Province. In 1991, he was appraised by Hebei Education Committee as "the most recent science and technology worker". In 1990 and 1991, he was recommended by the United Kingdom and the United States as a world achievement figure. Approved to enjoy special government allowances in 1992. In 1995 won the title of outstanding expert in Hebei Province. In 2001, he won the 7th Li Siguang Geological Science Award.
