Seed-plant flora in Khunjerab National Park of Pakistan
摘要
Abstract
Khunjerab National Park (the national nature reserve) was founded in 1975 with the total area of 2 270 km2, located in the northern part of Pakistan and southern sloping fields of the Karakorum Mountains, between latitude 36°04' ～37°05'N and longitude 74°38' ～75°45'E,with an elevation of 3 200 ～6 000 m, averaging4 000m above sea level. In the park, there is a section of 60km long China - Pakistan - Karakoram Highway. In order to protect to the utmost the grass, woods and the proto - vegetation in the course of building the highway, the author of this paper conducted an on - the - spot investigation in the park in September 2009. Through the investigation and consulting related literatures, the author analyzed the plants of the area from the point of floristic composition and features. The result shows that there are 38 families, 149 genera and 369 species of wild seed plants, among which there are 2 families, 2 genuses and 5 species of gymnosperm, 36 families, 147 genera and 364 species of angiosperm. According to Mr. Wu Zhengyis classification of the 15 distribution patterns of seed plants in China, the analysis on the geographical elements of the seed plants shows that the plants distributing in this area can be classified into 10 distribution patterns and 13 variations, of which the numbers of genera and species distributing in the north temperate zone are the largest with 72 genera and 199 species, making up 56.68% and 71.56% respectively of the total number of the genera and species in this area. This indicates the temperate zone property is the basic characteristic of the flora in the area. Meanwhile, most interflows between the flora in this area with that in the Old World temperate zone, Mediterranean - Western Asian - Central Asian, some interflows with the temperate Asian and Eastern Asian flora, and few ones with the tropical flora have been identified. Through the investigation and analysis it has been found that within the above mentioned 60 km long highway section of the Karakorum Highways in Khunjerab National Park, the plant species are relatively poor, while angiospermous plants occupy a dominant position. It is richer in high - and - cold polster plants, and lack of relict species, endemic species as well as species of arbor. Meanwhile, the floristic characteristics are of typical temperate zone in this area. These phenomena can be said to be the results of the high elevation, the cold and dry weather, the poor quality of soil, the geographic location of the area in question, and uniquely natural and geographic conditions.关键词
