中国野生稻的现状调查

A survey of the current status of wild rice in China

中国有三种野生稻。野生稻是栽培水稻的野生近缘种，已被列为濒危植物［７］，它们分布于中国南方８个省（区）的热带、亚热带湿热生境中。近年来人为的干扰和生境的破坏已导致它们的居群大量绝灭，其中濒危程度最高的是普通野生稻。本文阐述了它们的生物学、生态学特性，研究了它们的群落学特征，初步报道了它们的濒危状况。

There are three species of wild rice,which are wild relatives of the cultivated rice and listed in endangered plant species in China . They are distributed in humid areas of tropical and subtropical regions in eight provinces of southern China. Recently, human disturbance and destruction of habitats have led to the extinction of a great number of populations,of which Oryza rufipogon Griff. is the most endangered species. In this paper,their biological and ecological characteristics were described and the plant communities were also studied. Meanwhile, the endangered status and the reasons of wild rice in China were discussed.
