摘要:
通过对重庆金佛山国家自然保护区山顶和山坡10个不同植被类型的表土调查和采样,研究该区表土孢粉组合特征及其差异性。结果显示:1.山顶和山坡针叶乔木花粉(主要为马尾松)的含量均较高,山顶为9.29%～16.15%,山坡为25.37%～56.30%;2.阔叶乔木花粉在山顶含量较高(25.44%～39.28%),山坡含量较低(6.17%～17.25%);3.灌木花粉除JFS-1的含量较高(29.77%)外,其他样点含量均较低,山顶为6.24%～29.77%,山坡为6.08%～9.50%;4.陆生草本植物花粉除JFS-4含量较高(18.24%)外,其他样点含量均较低,山顶为6.43%～18.24%,山坡...
Abstract:
Through survey and sampling to 10 different vegetation types topsoil of mountaintop and Mountainside in Mt.Jinfo Nature Reserve,Chongqing of China, to study the features and differences of the sporepollen assemblage. The results show that:(1) peak and the slopes of coniferous tree pollen (mainly Pinus massoniana Lamb) content are higher, the peak is 9.29%~16.15%, 25.37%~56.30% for the slopes; (2) broadleaved tree pollen is higher in the Peak (25.44%~39.28%), the slopes of content is lower (6.17%~17.25%);(3) shrub pollen addition JFS-1 is higher (29.77%), other samples are lower, the Peak to 6.24%~29.77%, the slopes is 6.08%~9.50%; (4) terrestrial herb pollen is higher besides JFS-4 (18.24%), the content of other samples are lower, peak is 6.43%~18.24%, slope is 5.58%~9.52%; marsh grass pollen is only found in a small amount of JFS-5 (0.14%);(5)peak and the slopes of fern spores’ content are relatively high, the peak is 19.73%~ 46.77%, slope is 43.42%~22.60%.The surface sporepollen assemblage better reflect the composition of modern vegetation and can better reflect the basic characteristics of plant communities Karst in Peak and the slope of study area, and the results will provide important and improved information for the rehabilitation and reconstruction of karst mountainous region and the study of Quaternary paleovegetation、paleoclimate and palaeoenvironment etc.in the Mt.Jinfo areas.
