摘要
该研究采用样方结合样线调查的方法,并综合文献资料,于1983年和2013年2次对帽儿山国家森林公园植物种类进行实地调查,并进行了区系特征的对比分析,为评估帽儿山国家森林公园植物保护状况提供依据。结果表明:(1)2013年研究区的植物科数量和组成与1983年相同,但2013年比1983年少20属60种,不同等级科组成差异较小,而不同等级属差异较大。(2)优势科组成差异较小,但2013年兰科(Orchidacea)由优势科变成了非优势科,而藜科(Chenopodiaceae)和松科(Pinaceae)由非优势科变成优势科;优势属组成差异较大,2013年比1983年少了8个优势属。(3)2次调查表征科组成变化较大,但表征属组成差异较小,2013年比1983年少了2个表征属。(4)1983年和2013年科、属、种的分布型均以温带性分布为主;科的分布型完全相同,属的分布型2013年比1983年少了地中海区-西亚至中亚分布型;种的分布型,2013年比1983年多了亚洲-北美-北极分布。研究认为,30年间帽儿山国家森林公园的植物区系构成基本稳定,说明对这一区域的植物保护总体有效,但属和种的数量明显减少,30年间物种多样性显著降低,尤其是某些重要的科,如兰科植物的减少,也说明植物保护现状依然不容乐观。
In order to provide basis for assessing the plant protection of Maoer Mountain National Forest Park,we investigated plant species of Maoer Mountain National Forest Park twice on the spot in1983and2013by the method of sampling and sample survey,and analyzed the floristic characteristics.The results showed that:(1)compared with1983,the number and composition of families were the same.However,20genera and60species decreased in2013.The difference in the number of families at different levels is small,but the difference in the number of genera at different levels is large.(2)The difference in the composition of the dominant families was smaller,but in2013,Orchidaceae became a non-dominant family from the dominant family,while the Chenopodiaceae and Pinaceae became the dominant family from the non-dominant family.The number and composition of the dominant genera was different,decreased eight.(3)The two surveys showed a large change in the number and composition of typical families,but the difference in the number and composition of the typical genera was smaller,in2013compared to1983,only2typical genera decreased.(4)In1983and2013,the geographical composition of the families,genera and species were all dominated by temperate distribution.The geographical composition of the families was the same,and the geographical composition of the genera was less than that of the Mediterranean-West Asia to Central Asia in2003.In the geographical composition of genera,there was a lack of Mediterranean-West Asia to Central Asia in2013,but in the geographical composition of species,there were more Asia-North America-Arctic distribution than in1983.According to the research,flora composition of Maoer Mountain National Forest Park in30years is basically stable,indicating that the plant protection in this area is effective.But the number of genera and species decreased significantly,and the species diversity was significantly reduced in30years,indicating that the status of plant protection was still not optimistic,especially in some important families,such as the reduction of Orchidaceae plants sounded the alarm for plant protection in this area.
