Study On The Vertical Distribution And Introduction Domestication Of Broadleaved Evergreen Woody Plants In Henan

Funiu Mountain on the west in the Henan, the region in this thesis is located in the north-south wide of 40～70km. it lies between 110°30′～113°05 E, 32°45′～34°00′N, covering an area of about 10000 km2. The complicate terrain features of the area make it possbile to have rich plant resources. In this study, it is also usefull for the exploitation and utilities of the plants resources in Funiu Mountain.According to the speciments of evergreen broad-leaved woody plants identified by the auhtor, and analysis of the temperature factor. According on the results were as follows:1. The obvious character of transition and ancient in the flora.There are 31 families, 48 genera, 104 species(including subspecids) of evergreen broad-leaved woody plants in Funiu Mountain. Based on the opinion of Professor Wu Zheng-yi about the areal-types of Chinese genera of seed plant, the flora of the seed plant in evergreen broad-leaved woody plants of Funiu Mountain can be classified into 11 geography element make up the majority, approximating to 56.73% of the entirely knowen evergreen broad-leaved woody plants in Funiu Mountain, and nect come to Temperate elements, accounting for 31.73%. E.Asia elements is about 9.62%.To all appearance: the evergreen broad-leaved woody plants of the area is provided with Pantropic distribution elements and have obvious Temp. elements which showed the obvious character of transition in the flora.(2) The boundary of horizontal distribution——North subtropical and warm temperate ridge line is Funiu Mountain.There are 31 families, 48 genera, 104 species and varieties in Funiu Mountain; 30 families, 42 genera, 87 species and varieties in Dabie Mountain; 28 families, 35 genera, 55 species varieties in Tongbai Mountain; 5 families, 5 genera, 7 species in Taihang Mountain.The southern slope of Funiu Mountain that contains all of families, genera, species, but there are only 12 families, 13 genera, 23 species in northern slope. So, the best species source region of introduction domestication of the evergreen broad-leaved woody plants in Funiu Mountain Ridge (North subtropical and warm temperate line), including the southern slope of Funiu Mountain, Dabie Mountain, Tongbai Mountain.3. The boundary of vertical distribution——the north boundary of subtropical zone should be between 1000m and 1200m.The wealth of evergreen broad-leaved woody plants in Funiu Mountain with a vertical distribution of 2300m. the average annual temperatres 4.41℃. Distribution of hottest month in July the registy,the average temperature of 14.985℃. The coldest month in January, the average temperature of -6.785℃. The cumulative temperature of 1535.8℃(≥10℃), 130 days above(≥10℃), close to cool temerate zone. According to subtropical climate index, the cumulative temperature of 4500℃～4800℃to 6100℃～6300℃(≥10℃), the average temperatures of January is 0℃-4℃, the concentrated distribution in the upper limit of the vertical distribution of 1000～1200m in the most evergreen broad-leaved woody plants(51 species, 49%, the study suggests that north boundary of subtropical zone should be between 1000m and 1200m.4.There are 16 families, species plants of introduction domestication in Henan. According on the analysis shows that the species of small and single, its can not meet the needs of landscape green. In this study, the analysis of cultiration status and species source areas and proposed strategies in order to provide theoretical guidance for the workers.
