In six selected areas of the subtropical semi - humid evergreen broad - leaf forest ecosystem of yunnan diaolin mountain, during drought season from november, 1992 to april, 1993, authors studied and analysed, throught adopting the taxonomic, ecological and mathematical statistics method, the distribution, composition and domi - nant fungi of the small fungi as well as biodiversity. altogether 706 strains statistics unit, belonging to 28 genera, dominant fungi 678 strains statistics unit, 20 dominant fungi gen - era

    在雲南雕林山亞熱帶半濕潤常綠闊葉林森林生態系統的六個具有代表性的樣區中，於1992年11月至1993年4月旱季期間，運用系統分類、生態分析和數理統計的方法，對小型真菌種群的分佈、組成、優勢菌及其生物多樣性進行了分析，共分離獲得小型真菌菌株統計單位706株，分屬於28個屬，其中，優勢菌678株，分屬於20個屬。
  2. Statistics of the area of land use are gathered based on nine categories of land, including the cultivated land, garden land, forest land, grassland, other agricultural land, land for residential areas and mining, land for traffic, land for water facilities and idle land

    土地利用面積按耕地、園地、林地、牧草地、其他農用地、居民點及工礦用地、交通用地、水利設施用地和未利用地九大類進行統計分析。
  3. In six typical areas of huoditang mts, 48 genera of the small fungi is isolated from the forest litter. 277 strams statistics unit belong to 17 dominant fungi genera

    摘要在秦嶺火地塘6個代表不同生境的樣區中，從其森林凋落物中分離到48個屬的小型真菌，其中優勢菌17個屬，共277個菌株。
  4. 1. based on the data of analysis, using theories and methods of mathematical statistics, two of interception models by canopy of picea crassifolia are established as follows : the regression model on the relationship between penetration rainfall ( p, ) inside forest and total rainfall ( p ) outside of forest : pj = 0. 8245p - 1. 372 ( r = 0. 99 ) ; the model on the relationship between interception rate ( ir ) and rainfall : ir = - 10. 7111n ( p ). ( r = 0. 7524 ) the results show that penetration rainfall inside forest increases with total rainfall outside of forest in linearity, and to certain extent, penetration rainfall inside by canopy also increases with total rainfall outside ; the correlations of the interception rate to rainfall and intensity of rainfall are significant and the intercepted rate by canopy of picea crassifrlia is diminished with the increase of rainfall and rainfall intensity, and increase with the increase of canopy density

    1在利用數理統計原理和方法對實測資料進行綜合分析的基礎上，建立了青海雲杉林林冠截留降水模型：林內透過雨量與降雨量回歸模型： p _ i = 0 . 8245p - 1 . 372 （ r = 0 . 99 ） ；林冠的截留率與降雨量的模型： i _ r = - 10 . 711ln （ p ） （ r = 0 . 7524 ） ；分析模型表明：林內透過雨量與降雨量呈良好的線性關系，在一定的降雨量范圍內，林內透過雨量隨降雨量的增加而增加；林冠截留率與降雨量、降雨強度之間也呈良好的關系，林冠截留率隨降雨量和降雨強度的增大而減小，隨郁閉度的增加而增大。
  5. As soil and water loss is the main ecological environmental issue in the loess plateau, departments of water resources, forest, planning, civil administration and others are rushing into actions for returning cultivated slope lands into forest and grass, resulting in repeated input and achievement statistics. the out - of - order activities and false reported figures make it very difficult to reach expected objectives

    水土流失是黃土高原主要的生態環境問題，現在水利、林業、計委、民政等部門都在搞退耕還林還草，其結果是重復投資、重復統計成績，上報數字為虛玄數字，很難達到預期效果。
  6. In addition, by means of landscape diversity, evenness, dominance, fragmentation, fractal dimension and statistics, the author respectively analyzed landforms, plant, soil and so on in the original ecosystem of the typical dumping site, the damaged ecosystem and the rehabilitated ecosystem. in fact, landscape matrix has been completely converted from the original ecosystem to the rehabilitated ecosystem. the indexes of diversity, evenness and dominance in forest landscape have sharply increased, but segregation decreased, which demonstrates that the rehabilitated ecosystem has been a reasonable and fine artificial ecosystem under the control of human

    在此研究的基礎上，採用景觀多樣性指數、優勢度指數、均勻度指數和破碎度指數，以及分維方法和統計分析相結合的方法，對礦區典型排土場的原生態系統、破壞后的生態系統、重建生態系統的地貌、植被、土壤等景觀要素進行了分析，結果表明：從原生態系統到重建生態系統，景觀基質發生了根本性的變化，林地的多樣性、均勻性、優勢度大幅度增加，分離度降低，顯示了重建生態系統在人為的調控下，已初步形成一個結構較為合理、功能良好的人工復合生態系統。
  7. It consists concretely of data management, information indexing, statistics analysis, selecting measures and foreseeing forest resource, help system modules and etc. every modules can be run autonomously to improve the independence of the system in order to manage and assert the system

    系統可以實現數據管理、信息查詢、統計分析以及根據經營目標選擇經營措施等功能，並且可以預測未來的資源變化和消長情況。組成系統的各模塊之間相互獨立運行，增強了系統的獨立性，便於系統的管理和維護。
