摘要:
要想恢复秀美的山川,主要在于恢复被人类严重破坏的原始植被。黄土高原的原始植被到底 是什么样子,学者们说法不一。孢粉分析是最重要的方法。目前,研究结果已揭示出黄土高原古植被在 第四纪以来显示着时间上、空间上的变化。古土壤代表间冰期夏季风盛行的湿热气候,植被比较繁盛; 黄土代表冰期冬季风盛行的干冷气候,植被凋凌。全新世中期5000～6000年前,现代间冰期气候最佳 时期,半坡人生存之时,森林茂密并有亚热带植物入侵,但兰州一带1万年来一直保持着荒漠草原的面 貌。因此,黄土高原植被的恢复应参照各地的原始植被并考虑现代气候条件,因地制宜地实施。在东南 部可以恢复森林,中西部可以恢复森林草原,西北部只能种草恢复草原。
Abstract:
The beautiful landscape of the loess plateau in northern China could be primarily reconstructed by means of restoration of its original vegetation that was currently lost due to mankind' s destruction.The first task to do so involves clarifying the contentious type of the original vegetation through pollen spore analyses.Temporal and spatial changes of the paleo-vegetaion types in the loess plateau were figured out in terms of previous specific pollen spore-based studies.The paleo-soil was the product of the warm and humid climate predominated by the summer monsoon during the interglaciation , implicating a luxuriant period of vegetation , whereas the loess was related to the arid and cold climate predominated by the winter monsoon during the glaciation, indicating a withering period of vegetation.During the Banpo man time or in the Middle Holocene , 5 000～ 6 000 Bp , the climate within the modern glaciation best fitted vegetation and the intrusion of some sub-tropic trees was postulated to have taken place .Yet the Lanzhou area , Gansu Province , kept being desert or steppes for past 10 000 years .Consequently , the reconstruction of vegetation to its primary state should be principally implemented in consideration of its original distribution .Specifically , the southeast part of northwestern China should starts with forest and the middle part better with both forest and steppes while the west part can only be constructed as steppes .
