A PRILIMINRY STUDY ON THE MICROBIAL BIOMASS OF DEGENERATIVE GRASSLAND IN XILIN RIVER BASIN

Zhang Guizhi Liao Yangnan(Biology Department, Inner Mongolia University)  
A contrast analysis of the microbiol biomass of all kinds or soil microorganisms and plant above ground biomass on degenerative grassland dominated by Aneurole pidium chinense in all the test regions indicate that artificial measures such as enclosure,inside fence ploughing and sowing A.chinense, harrowing and sowing A.chinense have improved intensity of soil activity considerably, and increased productivity of degenerative grassland, too.This analysis also indicate that all the above-mentioned artificial measures can bring different degree of restoration and improvement to degenerative grassland.
