Study on microclimates of different ecosystems in hilly red soil areas

Comparative analysis and correlation analysis of microclimates in 6 ecosystems of Phyllostachys praecox , Cunninghamia lanceolata , Pinus elliottii and Paspalum notatum , Cunninghamia lanceolata and Pinus elliottii , Citrus grandis `Changshanhuyou' , in hilly red soil areas of Jinhua-Quzhou Basin , Zhejiang Province , were conducted .The results of comparative analysis showed that Cunninghamia lanceolata and Pinus elliottii was most effective to regulate the soil humidity , air relative humidity and Phyllostachys praecox was the most effective to regulate air temperature .The correlations of 6 ecosystems were 0.781 6 , 0.738 4 , 0.823 4 , 0.759 5 , 0.712 2 and 0.741 8 respectively .As far as the regulation of all three factors including soil humidity , air relative humidity and air temperature was concerned , Cunninghamia lanceolata and Pinus elliottii functioned the best .[ Ch , 3 fig .1 tab .11 ref .]
