    本文研究了茄子不同品种的群体结构与产量构成因素的变异,大田群体的不同叶层的光强分布及一天中的变化。当太阳光照射到大田以后,大部分为叶面所吸收,但也有一部分被反射及透光。 试验还测定了茄子光合作用强度因光照强度及叶龄的不同所发生的差异。夏季中午的光合作用强度有“午睡”现象。光合作用的饱和点在2.5─3万米烛光左右,而补偿点在500─1,000米烛光之间。 叶龄15─35天是光合作用最旺盛的时期。也是相当于单叶面积绝对生长量最大而叶绿素含量最高的时期。计算群体的光合作用时,不仅要考虑群体的光强的垂直分布,而且要考虑到不同叶龄的垂直分布。在生产上的整枝摘叶措施,应利用这一特性。

    The biological effects of the community structure of one artificial rubber forest were observed with the modern instruments and the traditional microclimate 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 directly 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. But they were not only influenced by the environment but also subjected to the regulations of the rubber trees themselves. During the winter, the thermal effect was more obvious on the rubber forest border than in the forest deeps. The temperature of the forest border was 2 ℃ higher than that of in the forest deeps. This kind of temperature difference may be used in the cold prevention on artificial rubber forest. Since the temperature of rubber trees is different from the air temperature. While the air temperature changes relatively limited. This difference of temperature variation is favourable to the normal growth of plants. It is proposed that to measure the temperature of rubber trees can be used in the observation of cold injury. It is useful to cultivate some tea trees in rubber forest to increase the forest temperature in winter. It is not an ideal method of cold prevention to apply a black coating on the trunks of rubber trees because the increase of the temperature on the forest border is not much obvious in winter. Moreover, if such method to be used in rubber forest deeps, there would be a tendency of slight decrease of the temperature which may increase the cold injury to rubber trees.

    采用近代仪器与传统小气候观测相结合的方法,研究了人工胶林群落结构的生物学效应;对若干生态因子变化规律进行了初步讨论。胶树体温与测试地日照强弱密切相关。西双版纳树温西南高,东北低,西向与北向最高温之差约为1℃;树表和浅层受日照影响直接而明显,随深度增加而减弱,树心比较间接,既受环境影响又受本身机体调节。冬季胶林边行热效应较明显,比林内树温高2℃左右,若加充分利用对防寒有一定意义。树温和气温有差别,气温变幅大,树温变幅小,有利于植物正常生活,建议直接测定树温观察寒害。胶林中适当种植茶树,冷季有增暖效果,能对轻度寒害起缓冲作用。涂黑树干法不是理想防寒措施,因边行增温不明显,况且密林深处有轻微降温趋势,可能导致寒害加重。

    Based on the tree and undergrowth species diversity measurement of 11 fore- st communities in Guangdong subtropic,this paper deals wilh the distributional regularity and practice importance of forest species diversity. preliminary results are: (1)The species diversity increases from coniferous forest to coniferous- broad-leaf forest and then to broadleaf forest.But in the latter stage,species diversity of coniferous-broad-leaf forest is quite high,near broadleaf forest。 (2)Species diversity has a relation to community structure.It goes up with the ascent of homogeneity and goes down when the dominance of dominants increases. (3)In the range of Guangdong subtropical forest,species diversity becom- es lower when latitude becomes higher. (4)In the developing forest,species diversity becomes higher from the canopy sublayer to the second sublayer to the third sublayer while it chang- es conversely in the degenerative forests.
