红色叶树种资源及其在园林中的应用

为了摸清我国园林植物中叶片为红色的树木种质资源，通过查阅文献和实地调查，结果表明，我国红色叶树种约28科55属92种,主要分布在落叶树种中的蔷薇科、漆树科、槭树科等和常绿树种中的小檗科、金缕梅科、卫矛科等科，如紫叶李、紫叶矮樱、紫叶桃、紫叶小檗和南天竹、红花檵木、石楠等。有些还是比较稀有珍贵的种类，如蓝果树、大果领春木、连香树、野鸦椿等。加强红色叶树种的研究与推广应用，不仅可以保存现有种质资源，还能为园林绿化增色添彩。

PRELIMINARY STUDY OF THE RESOURCES AND USAGE OF WOODY PLANTS WITH RED LEAVES

In order to know the real situation of the woody plants with red leaves of ornamental plants in our country, a great number of reading up the literature and investigation have been done. It shows that there are about 28 families and 55 genera and 92 species of woody plants with red leaves in our country. They are chiefly in the families of fallen-leaves plants such as Rosaceae,Anarcardiaceae,Aceraceae and in the families of ever-green plants such as Berberidaceae,Hamamelidaceae and Celastraceae etc, and some of them are the rare and precious species. We should research and spread these species more so as to preserve the germplasm and color the landscape.
