Abstract: The biological effects of the community structure of onr artificial rubber forest were observed with the modern instruments and the traditional microcli-mate observations. The variation regularity of some ecological factors was preliminarily discussed. It was observed that the temperature of rubber trees and the sunlight intensity at the experimental locality were closely related. In Xishuan-banna, the rubber tree temperature of facing southwest part is higher than that of facing northeast part. The highest temperature difference between W and N parts of rubber trees was 1 ℃. The temperatures of the surface and shallow parts of the rubber trees were directIy and obviously influenced by the sunlight intensity. And the influence was gradually reduced to the deeper parts of the rubber trees. The core parts of the rubber trees were indirectly influenced by the sunlight intensity.。
