Hong ZHANG, Jialong LU, Shiwei ZHAO,

Frontiers of Environmental Science & Engineering 2009, Volume 3, Issue 4,   Pages 421-427 doi: 10.1007/s11783-009-0147-8

Abstract: This study investigates the changes in soil microbial populations as vegetational succession progressfrom abandoned farmland to climax forest in the Ziwuling Forest, which is located in the northern partSoil microbial C was calculated using ec=0.38 and microbial N was calculated using en=0.45.Soil bacteria, fungi, and actinomycetes increased as the vegetational succession progressed.There was a significant correlation between microbial biomass and soil nutrients.

A New Way to Study the Three Essential Factors of Forest Fire

Zhao Xianwen

Strategic Study of CAE 2000, Volume 2, Issue 5,   Pages 66-71

Abstract:

This thesis took the three essential factors of forest fire (fire source, environment, and litter)as the point of departure,and has approached the forecast method of forest fire in tropical area ofFor example,in the aspect of forest fire forecast, the main cause of forest fire was artificial fire,In the aspect of the analysis of environment that contributes to forest fire,correlation would revealIt provided an effective and quantitative way with higher reliability for forest fire forecast on region
