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。
The composition of non-food diesel energy plant in Songnen grassland was analyzed by the combination of field investigation and reference data. The results showed that the non-grain diesel energy plants in Songnen grassland included 75 species, 20 genera, 54 genera and 20 temperate species, with the world’s distribution accounting for the vast majority (70%). The northern temperate distribution is the highest (25.93%), with the largest proportion (18.57%) of the China-Japan distribution and the Old World temperate distribution. It is mainly divided into 5 districts and subregions. The non-food diesel energy plants account for 19.93% of the plant area in Northeast China, NE of plant area in North China (18.92%), 22.64% of NEEP in Northeast China Mongolian steppe sub-region component (EMS) accounted for 19.59%, Daxinganling plant component (DA) accounted for 18.92%. Temperate nature of the plant is very obvious, save a considerable number of adjacent areas of non-grain diesel energy plant resources, resource plant reserves, have good development prospects.
