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.
