| 摘要: |
| 通过野外踏查和查阅资料相结合的方法对松嫩草地的非粮柴油能源植物组成进行分析。结果显示:松嫩草地非粮柴油能源植物包括20科54属75种,温带性质明显,世界分布科占绝大多数(70%)。北温带分布型的属所占比例最高(25.93%),中国-日本分布型和旧世界温带分布型的种所占比例最大(18.57%)。主要分5个区和亚区,非粮柴油能源植物中东北植物区成分(NE)占19.93%,华北植物区成分(NC)占18.92%,东北平原亚区成分(NEP)占22.64%,东蒙古草原亚区成分(EMS)占19.59%,大兴安岭植物区成分(DA)占18.92%。本区植物温带性质十分明显,保存了相当数量的相邻区系的非粮柴油能源植物资源,资源植物储备量大,有很好的开发前景。 |

| Abstract: |
| The non-food plant resources for biodiesel were surveyed by the range reconnaissance and resourcing approaches in Songnen Grassland.There were 75 species of halophytes in 20 families and 54 genera.Distribution of the non-food plant resource for biodiesel families and the energy plants genera showed that the flora had a diverse geographical characteristic with an overwhelming numbers in temperate regions.Over 70% of the majority of families were Cosmopolitan.North Temperate was the maximum type genera (25.93%),Old World Tropics and E.Asia were the maximum type species.The faunistic component is NC:18.92%,NEP:22.64%,EMS:19.59%,DA:18.92%,NE:19.93%,respectively. |
