Abstract


The Funiu Mountain is located in western Henan, geographic coordinates of longitude 110 ° 30 'to 113 ° 05' north latitude and 32 ° 45 'to 34 ° 00'. Was a southeast to northwest, east and west stretches about 400km, south width of 40 ~ 70km area of ??about 10,000 km2. The forest coverage Funiushan, evergreen broadleaf plants rich resources, this study hopes to provide a theoretical basis for the rational development and utilization of plant resources and protection as well as introduction and domestication. Identification to collect specimens and Herbarium specimens and the temperature factor of the evergreen broad-leaved woody plants. The results of this experimental study are as follows: 1. Ancient flora the transition significantly Funiushan evergreen broadleaf woody plants and 31 families, 48 ??genera and 104 species (including subspecies). This study will be divided into 11 types of world ingredients, pan-tropical ingredients Funiushan evergreen broad-leaved woody plants flora. Tropical ingredients most prominent, accounting for 56.73% of the total number of species of evergreen broad-leaved woody plants in the region, followed by temperate elements, 31.73% of the total number of species, East Asian ingredients also contain 9.62% of the total number of species, indicating that the both subtropical evergreen broad-leaved woody plants Funiushan flora, there are many warm temperate flora composition, showing the transitional flora. Level of climatic zones - barberry ridge north subtropical and warm temperate dividing line Funiushan 31 families, 48 ??genera and 104 species; Dabie Mountains, 30 families, 42 genera and 87 species; the 28 families Tongbaishan, 35 genera, 55 kinds; Taihang 5 families, 5 genera, 7; widely distributed groups of four major mountain 4 families, 4 genera, 6. Barberry southern slope includes all subjects of the mountain, is a species; while the northern slope of only 12 families, 13 genera and 23 species, Henan evergreen broad-leaved woody plants Introduction and cultivation of the best provenance areas Funiushan ridge The (northern subtropical and warm temperate boundary) south of the North subtropical evergreen broad-leaved plant distribution, including southern slope Funiushan, Dabie Mountains and Tongbaishan,. Vertical climatic zones - Funiushan the southern slope of the northern subtropical vertical boundary at an altitude of 1000m ~ 1200m Funiushan the rich evergreen broad-leaved woody plants the highest vertical distribution of up to 2300m. The premises years the average temperature was 4.41 ℃. Distribution upper limit of the average temperature in July, the hottest month 14.985 ℃, the coldest month in January the average temperature to -6.785 ° C accumulated temperature ≥ 10 ° C 1535.8 ° C ≥ l0 ° C days to 130 days, close to the edge of the boreal. According to the subtropical climate indicators by: ≥ l0 ° C days 218 to 239 days; ≥ 10 ℃ accumulated temperature of 4500 ℃ ~ 4800 ℃ to of 6100 ° ~~ 6300 ° C; 1 January the average temperature of 0 ° C to 4 ° C. Maximum vertical distribution of the most Funiushan evergreen broad-leaved woody plants (51, 49%) is concentrated in the 1000 ~ 1200m, the study recommended the northern subtropical southern slope of Funiushan vertical boundaries at an altitude between 1000m ~ 1200m. Introduction and domestication of plants in Henan, 16 families, 48 ??species by their analysis shows that the type of introduction and cultivation of small and single, can not meet the demand for landscape planting. In this study, analysis of its the cultivation status quo and provenance, and proposed countermeasures to provide theoretical guidance for the introduction and domestication of workers.
