摘要: [目的] 分析我国淀粉植物区系的特点及其在不同海拔、不同气候区域的分布情况,为进一步针对不同区域因地制宜开发淀粉植物奠定基础。[方法] 搜集在我国分布的171种淀粉植物的地理分布数据,分析不同地理环境区域内的分布情况,并对其属的区系地理分布进行分析。[结果] 我国淀粉植物属的地理分布温带成分占主导,热带成分的也占重要地位。85%以上的淀粉植物在海拔1000m以下有分布,并随着海拔升高淀粉植物分布减少。温度和降水量对淀粉植物的分布影响较大,超过80%的淀粉植物分布在秦岭淮河以南湿润的亚热带区。[结论] 我国淀粉植物有较高的物种多样性,其地理分布也复杂多样,但是目前对野生淀粉资源的开发利用较少,应因地制宜,根据不同的地理环境发掘不同的淀粉植物,使其更好地应用于边际土地非粮生物质能源的开发。

Abstract: [Objective] The objective of this case was to give basis suggestions for further development and utilization of starch plant in different regions,according to analyze the distribution characteristics in different elevations and climatic zones of the starch plants flora in China.[Method] The distribution data of 171 starch plant in China were collected for analyzing the distribution of starch plant in different climatic zones.The areal-types of genera of the starch plants in China were also been analyzed.[Results] The results indicated that,the temperate type is the main type of the areal-types of genera of the starch plants in China,as well as tropical types.More than 85% of the starch plants distribute at an altitude of 1 000 m or less.and the amount of starch plant reduces with the increase of altitude.The temperature and precipitation greatly impact on the distribution of starch plants.More than 80% of the starch plants distribute mainly in humid subtropical zone,which is in the south of the Qinling mountain/Huaihe river.[Conclusion] The starch plants in China have higher species diversity and complex geographic distribution.But the development and utilization of starch plants in China is limited,especially for wild plant resources.It should increase its development and utilization,and explore different starch plants depending on the geographical environment for the development of non-food bioenergy plant in marginal land.

Key words: starch plants, geographic distribution, flora, elevation, climatic factors
