以贵州省施秉喀斯特世界自然遗产地为研究区
对区内苔藓生境类型及微气候效应进行了研究。结果表明
苔藓植物群落可以影响其周围局地微气候
具有降低气温
增加湿度的作用。苔藓微气候效应影响范围大致在四周及上方10 cm空间内
在空旷地上微气候效应最为明显。该区苔藓生境类型以岩生、土生为主
土生苔藓植物群落的微气候效应强于岩生环境。对各监测层的温湿度分别进行配对样本t检验
结果发现
苔藓群落表面(A层)与周围10 cm处(D层)相对湿度差异极显著(p<0.01)
温度差异达显著水平(p<0.05);苔藓群落表面(A层)与上方10 cm处(B层)温、湿度差异均达显著水平(p<0.05)。苔藓微气候效应的强弱程度取决于苔藓储存水分的能力。
The microclimatic effects and habitat types of bryophytes were observed in karst world natural heritage nominated property of Shibing County in Guizhou Province. The results showed that bryophyte communities could affect the surrounding microclimate by lowering the air temperature and increasing the relative humidity. The microclimatic influencing sphere of of bryophytes was almost within a radius of 10 cm. The most significant microclimatic effects were found in open space. The results of paired-sample test showed that the difference of relative humidities between layer A(the surface of bryophyte community) and layer D(10 cm horizontally away from the bryophyte community) achieved very significant level(p<0.01)
and that the temperature difference between layer A and D was statistically significant(p<0.05). Both the differences of relative humidities and temperatures between layer A and layer B(10 cm up the bryophytes) were statistically significant(p<0.05). The intensity level of the microclimatic effects depends on the water storing ability of the bryophytes.
