柳属(Salix L.)植物为分布广、种类多的一类林木资源。我国约250种,分布于全国,西南较为集中。我省林区、丘陵、风沙地及四旁皆有分布或栽培。由于过去未做专题研究,柳树资源底子不清。近年来,我们结合柳树良种选育工作的调查研究和编写《山西树木志》柳属标本、资料的收集,对山西柳树资源作了初步研究。一、山西柳树资源研究的基础过去省内柳树资源是作为整个植物资源的成员一并进行研究的。所以植物分类学家们的工作为我们的研究奠定了良好的基础。早在30年代,我国著名树木分类学家郝景盛教授对中国柳属(Salix L)做过深入的研究。1936年他首次发表了山西柳 Salixshansiensis Hao。在此前后,中外学者多次来山西考察采集。但是,更多的工作是在 Salix (Salix L.) plants are widely distributed, many kinds of forest resources. About 250 species in China, distributed throughout the country, the Southwest is more concentrated. Our province forest, hills, sand and all sides are distributed or cultivated. Due to the lack of special studies in the past, willow resources unclear. In recent years, we combine the investigation and research on the breeding of willow seeds and write “Salix specimens of Shanxi Shimushi” and collect the data, and make a preliminary study on the resources of willow in Shanxi Province. First, Shanxi willow resources research foundation Past willow resources in the province as a member of the entire plant resources together to study. Therefore, the work of plant taxonomists laid a good foundation for our research. As early as the 1930s, Professor Hao Jingsheng, a famous arborist in China, conducted an in-depth study of Salix L. In 1936 he first published Salix shansiensis Hao Shanxi. Before and after that, Chinese and foreign scholars came to Shanxi to study many times. But more work is here
