| Abstract
|
| [Objective] A systematic survey of Polygonatum plants in Tianjin has been made to determine the species classification and distribution area, estimate the reserves, lay the foundation for the further development and utilization. [Methods] The systematic sample method(sample method) and stratified sample method were adopted and setting a graded survey and stratified route were set, which included representative region→belt transect→sample plot→quadrat to investigate the frequencies and densities, measure biomasses and then calculate the reserves of all varieties. [Results] The Polygonatum plants, including P. sibiricum Red., P. macropodum Turcz., P. humile Fisch. ex Maxim. and P. odoratum (Mill.) Druce are widely distributed in Tianjin. These four kinds of plants are suitable to growth in the understory, shrub and dank strip of the altitude of 200 to 950 m. The reserves are about 1.056×106, 6.98×105, 3.45×105 and 1.26×105 kg. The P. sibiricum Red. and P. odoratum (Mill.) Druce are mainly distributed in Huangyaguan-Jiushanding and Baxianshan area; the P. humile Fisch. ex Maxim. are mostly distributed in Huangyaguan-Jiushanding and Jiulongshan area; the P. macropodum Turcz. are mainly located in Panshan and Jiulongshan area. [Conclusion] The various wild Polygonatum plants in Tianjin have abundant reserves having greater development value. |
