植物的特有现象与生物多样性

特有现象是生物多样性的依据，多样性是特有现象的体现，特圾现象是种系分化的结果，特有现象的成因是多方面的，包括地貌因子、土壤因子、气候因子、边缘效应、海洋岛屿隔离以及自然杂交。全球各大的自然条件的多样性，促成了各大陆各异的特有现象和生物多样性，生物多样性是生命运动的属性，它是在系统发育过程中发展壮大的，因此，它的发展有生的，既具有普遍性，又具有特殊性，保护生物多样性是当前的迫切任务。

Plant Endemism and Biodiversity

Endemism is the source of biodiversity, and biodiversity is the result of endemism. Endemism is based on the taxon differentiation, it is caused bythe different geomorphology, varied soils and climates, and by the edge effection,isolated oceanic isles and natural hybridation also. Since the variable environmental conditions, there were existed different endemism in each continent. Biodiversity is the property of biological phenomena, and developed along with the systematic development, it contains regularity of both universality and particularity. Biodiversitic protection is the priority work.
