摘要

以同在滇中地区磷素差异较大的富磷区与贫磷区的云南松林群落及其土壤为研究对象，采用Sui修正后的Hedley磷素分级，研究了土壤磷素的有效磷特征和土壤其他养分因子，分析了2类云南松群落的结构及其差异。结果表明，富磷区土壤全磷含量显著高于贫磷区，虽然两地活性磷（H2O—Pi、NaHCO3—Pi和NaHCO3—Po）含量都低于10%，但富磷区活性磷含量显著高于贫磷区，贫磷区有机磷含量高于无机磷含量，富磷区却相反；富磷区其他土壤养分如全氮、有机碳含量也显著高于贫磷区。富磷区云南松群落林木密度、Shannon-wiener指数、Simpson指数、Pielou指数均高于贫磷区云南松群落，而平均株高、平均胸径、冠幅低于贫磷区云南松群落。讨论认为，在贫磷区云南松与富磷区云南松群落的生长发育与营养策略有关，在磷素匮乏的地区，植物群落为了维持正常生长而进行紧密磷素循环，植物和微生物主要利用的磷素来自有机磷的矿化与溶解，并最大限度地减少生物地球化学循环的磷损失；但在磷素极其充沛的地区植物和微生物群落更加倾向将磷素从土壤矿石转移到生物地球化学磷循环中，对于当地植物和微生物来说，紧密的磷素回收就显得无关紧要。两地云南松群落结构的显著差异与地表磷素含量关系密切，富磷区因土壤磷含量丰富，并且引起其他营养资源丰富，从而能够维持更多种类的植物，同时相应地降低云南松在群落的生态优势；相应地贫磷区磷素成为限制因素，并且其他营养资源也相对短缺，从而不能支持更高水平的植物多样性，云南松因具有较强竞争力而生态优势更高。

Abstract

In this study

Pinus yunnanensis communities and their soils in the two places (phosphorus-rich area and phosphorus-poor area) with large differences in phosphorus content in Central Yunnan were taken as the research objects. The Hedley phosphorus classification revised by Sui was used to study the available phosphorus characteristics of soil phosphorus and other soil nutrient factors

and the structure and differences of two types of P. yunnanensis communities were analyzed. The results showed that the total phosphorus content in the phosphorus-rich area was significantly higher than that in the phosphorus-poor area. Although the contents of active phosphorus (H2O—Pi

NaHCO3—Pi

and NaHCO3—Po) were lower than 10% in both areas

the active phosphorus content in the phosphorus-rich area was significantly higher than that in the phosphorus-poor area. In the phosphorus-poor area

the content of organic phosphorus was higher than that of inorganic phosphorus

but it was the opposite in the phosphorus-rich area. The contents of other soil nutrients such as total nitrogen and organic carbon in the phosphorus-rich area were also significantly higher than those in the phosphorus-poor area. The forest density

Shannon-wiener index

Simpson index and Pielou index of P. yunnanensis community in the phosphorus-rich area were all higher than those in the phosphorus-poor area

while the average plant height

average DBH and crown width were all lower than those in the phosphorus-poor area. The growth and development of P. yunnanensis communities in phosphorus-poor areas and phosphorus-rich areas were related to nutrition strategies. In phosphorus-deficient areas

plant communities carried out a tight phosphorus cycle to maintain normal growth. Phosphorus mainly used by plants and microorganisms came from the mineralization and dissolution of organic phosphorus

and the phosphorus loss was minimized in the biogeochemical cycle. However

in areas where phosphorus was extremely abundant

plant and microbial communities were more inclined to transfer phosphorus from soil ores to the biogeochemical phosphorus cycle. For local plants and microbes

tight phosphorus recovery was irrelevant. The significant difference in the community structure of P. yunnanensis between the two places was closely related to the phosphorus content on the ground. Phosphorus-rich areas were rich in soil phosphorus and other nutrient resources

which was able to maintain more kinds of plants and correspondingly reduce the ecological advantages of P. yunnanensis in the communities. Accordingly

phosphorus had become a limiting factor in phosphorus-poor areas

and other nutrient resources were also relatively short

which could not support a higher level of plant diversity. P. yunnanensis had a higher ecological advantage because of its strong competitiveness.
