Abstract:This paper chiefly disscuses the characteristics of Shuo County flora and its significance in ecological economics. The results show:It is now known that there are 938 species of vascular plants in Shuo County, belonging to 420 genera and 105 families, among which 925 species of spermatophytes belong to 410 genera and 97 families. Among these 410 genera there are 11 monotypic, 15 oligotypic and 6 Chinese endemic ones.According to professor Wu Zhengyi‘s areal patterns of Chinese spermatophyte genera, there are 14 areal patterns in Shuo County. Among the patterns temperate zone ones make the largest percentage (69.9% of total genera). The flora of Shuo County, the nature of which is centrally temperate steppe zone, originated principally from Old North Continent.In comparison with other flora in China, We can see that the composition of Shuo County flora has the closest relation with Mongolia flora, andsecondly with Plateau floraThere are many economic plants in Shuo County, for example, there are 320 species of medicinal plants, 150 species of forage plants. Furthermore, exploitation, utilization and protection measures of plant resources in Shuo County are proposed in this paper.
