Study on Quantitative Distribution of Soil Microorganism and Relationship with Enzyme Activity and Physical,Chemical Property of Shelter forest in Rocky Coastal Area

The quantitative distribution of soil microorganism of different protective forest types in rocky sub tropical coast is studied.By means of mathematical analysis,the relationship of soil microorganism with enzyme activity,physical and chemical property is discussed.The results are as follows:①There is significant correlation among the three types of microorganisms.Major population is bacteria,followed by actinomycete,the least one is fungi.But the percentage of fungi is much higher than that in silting coastal areas.②The quantity of soil microorganisms in different forest types is quite different.There are more soil microorganisms in no timber forest,whereas the number is less in mature forest of Pinus massoniana and Myrica rubra.③There is a correlation between soil microorganisms and enzymes, but the coefficients are low. ④There is close correlation between soil microorganism and physical,chemical property.At last,some relative problems are discussed.
