海南热带雨林

雨林，熟悉的名字，陌生的场景。 3年后的今天，我依然清晰记得，我第一次进入热带的5个小时以前，还是身处在漫天飞雪的遥远北方。2003年北京的第一场雪伴送我前往机场，3个半小时的飞行，走下飞机，一股夹杂着南方树木独特味道的潮湿空气侵入我的鼻腔，顿时，我的呼吸器官体会到了从未有过的舒适感觉，这也在一定程度削弱了我对此次野外之行的陌生与畏惧。

Species association in tropical montane rain forest at two successional stages in Diaoluo Mountain, Hainan

Species association is one of the basic concepts in community succession. There are different viewpoints on how species interaction changes with the progress of succession. In order to assess these relationships, we examined species associations in the tropical montane rain forest at early and late successional stages in Diaoluo Mountain, Hainan Island. Based on data from a 2 × 2 contingency table of species presence or absence, statistical methods including analysis of species association and X ² tests were applied. The results show that: 1) an overall positive association was present among tree species in the communities during the two successional stages and were statistically significant at the late stage. The number of species pairs with positive and negative associations decreased throughout the process of succession, while the number with null associations was greatly increased. The same trend existed among the dominant and companion species. The results indicate that the communities are developing towards a stable stage where the woody species coexist in harmony. 2) In the early-established and later invading species, all positive associations were not significant. Compared with positive and null associations, fewer negative associations were found. This implies that these species are inclined to coexist independently through portioning of resources. 3) Among the later invading species, positive associations were significant and no negative associations were found which suggest that these species have similar adaptive ability in the habitat and occupied overlapping niches in the community. __________ Translated from Biodiversity Science, 2007, 15(3): 257–263 [译自: 生物多样性]

Rainfall-runoff responses and roles of soil moisture variations to the response in tropical rain forest, bukit tarek, peninsular Malaysia

Field observations were conducted at Bukit Tarek Experimental Watershed in Peninsular Malaysia to investigate the relationship between rainfall-runoff responses and variation in soil moisture in a tropical rain forest. Stormflow depended strongly on the antecedent wetness as represented by the initial runoff rate. Though heavy rains fell in almost every month, the soil moisture decreased when fair weather was sustained. The soil moisture depleted and became dry at 160 cm depth during occasional dry spells. During dry conditions, streamflow responded quickly to rain events but declined rapidly after the rain stopped, and the soil moisture of surface soil (≤20 cm) increased but remained dry at lower depths (≽80 cm). This suggests that the rain water was mostly retained in the soil and only small proportions appeared as stormflow. As soil moisture conditions became wetter, the recession limb of the storm hydrograph was more gradual. Stormflow volume increased with increasing soil moisture. During wet conditions, the soil profile was moist at all parts of the slope. The hydraulic gradient was around 1.0 and there was downward soil water flux, which followed the pressure gradient. This suggests that subsurface flow from the upper part of the slope might also be important for stream-flow production. Positive pressures were observed at 10 cm and 160 cm depths during large storms. The behavior of the subsurface flow might be an important determinant of stormflow.

Soil physical properties and preferential flow pathways in tropical rain forest, Bukit Tarek, Peninsular Malaysia

Soil physical properties and water movement within soil were investigated using dyes in a tropical rain forest, the Bukit Tarek Experimental Watershed of Peninsular Malaysia. The saturated hydraulic conductivity (K _s) decreased with increasing soil depth. TheK _s values were higher than those reported for other tropical soils. The geometric means of theK _s values ranged from 4.69×10⁻³ (80 cm) to 4.07×10⁻² cm s⁻¹ (10cm). This suggests saturation overland flow may not be dominant but that subsurface flow must play an important role in stormflow generation. The shapes of the soil moisture characteristic curves resembled those of forest soils which have large changes in volumetric water content at pressure heads <30 cmH₂O. The relatively high conductivities were due to the presence of a porous zone of decomposed root channels which existed continuously in vertical direction. Besides decayed roots, living roots also encourage preferential flow in vertical and lateral (downslope) directions. Termite activities may also form water flow pathways in tropical regions. These detailed results help us analyze water flow within the soil in tropical rain forests.     

Photosynthesis in relation to leaf nitrogen, phosphorus and specific leaf area of seedlings and saplings in tropical montane rain forests of Hainan Island, south China

In order to make clear the relationships between photosynthesis and leaf N, leaf P and SLA of tropical trees, and test the differences in the relationships among life-form groups (trees, shrub-like trees and shrubs), seedlings and saplings of 101 species from a tropical montane rain forest, located in the Diaoluo Mountain of Hainan Island, were selected. The net photosynthesis based on area and mass (A _area and A _mass), leaf nitrogen content based on area and mass (N _area and N _mass), leaf phosphorus content based on area and mass (P _area and P _mass) and specific leaf area (SLA) were measured and/or calculated. The results showed that A _area and A _mass tended to follow the order of shrubs > trees > shrub-like trees. One-way ANOVA showed that the difference in A _area between shrubs and shrub-like trees was significant (p<0.05), and for A _mass there were significant differences between shrubs and shrub-like trees and between shrubs and tree species (p<0.05). The relationships between A _area and N _mass were highly significant in all three life-form groups and for all species (p<0.0001). The correlation between A _area and P _mass was highly significant in shrubs (p = 0.0038), shrub-like trees (p < 0.0002) and for all species (p<0.0001), but not significant in trees (p>0.05). The relationship between A _area and SLAwas highly significant in shrubs (p = 0.0006), trees (p<0.0001) and for all species (p<0.0001), however this relation was not significant in shrub-like trees (p>0.05). The relationships between A _mass and leaf N and SLA were highly significant in all three life-form groups and for all species (p<0.0001). For A _mass and leaf P, there were significant correlations in tree groups (p = 0.0377) and highly significant correlations in shrub groups (p = 0.0004), shrub-like tree groups (p = 0.0018) and for all species (p < 0.0001). Stepwise regression showed that predicted A _mass values were closer to the observed values than those for predicted A _area values. Thus, it can be concluded that the relationships obtained from seedling and sapling measurements are close to those from mature individuals; correlations between photosynthesis and N _mass, P _mass and SLA traits are significant and the relationships are stronger and more stable for A _mass than for A _area. __________ Translated from Acta Ecologica Sinica, 2007, 27(11): 4651–4661 [译自:生态学报]
