Based on above - mentioned analysis, the strategy and measures to prevent the soil fertility quality degradation of artificial picea mature forest and improve the stand ecological environment were put forward, including the rational management of inter - cutting down and fostering after artificial picea forest matured. because conifer - hardwood forests generally contain more tree species than pure coniferous forest, and their structure also is more complex, forestation in subalpine of western sichuan should be conifer - hardwood forests
林地土壤有機質主要來源於凋落物的分解，並受其分解速率的控制，解決當前人工成熟林地土壤退化的主要措施應為林地凋落物分解創造條件，即因地制宜地對成熟人工林進行間伐或輪伐，當前在該區域造林應避免營造針葉純林。 -
Taxus chinensis var. mairei population in form. taxus chinensis var. mairei community using six aggregate indices ( c, i, i m, pai, ca, ), then analyze the causes of evolved pattern. the results indicated that the distribution pattern of seedling were all clumped in every plot, however, the distribution patterns of sapling, media tree and mature tree were mostly random. the trend of diffuse of form
）回歸分析法研究了南方紅豆杉林中南方紅豆杉幼苗、幼樹、中齡樹和成樹的分佈格局及動態，並分析格局形成原因，結果表明，各樣地南方紅豆杉種群幼苗均成聚集分佈，幼樹的分佈格局偏向于隨機分佈，而中齡樹與成樹則為隨機分佈，從幼苗到成樹，隨機擴散的趨勢十分明顯。 -
The seeding accounted for 91. 48 % of total number, and the mature tree of h : 5 ~ 7m class for 227 % whose density was just next to the seeding class. the results of intraspecific and interspecific competion formed the different individual height of taxus chinensis var. mairei population. the fractal dimension of taxus chinensis vsr. mairei were calculated on three indices : crown breath, base area, volume
分析南方紅豆杉種群高度結構變化的原因認為，種間和種內對資源的競爭是引起其種群結梅粼七的主要原因，隨著高度增長，物種間不唯琳內對生存空間的競爭加劇，形成南方紅豆杉種群世代不同大， j 、個體的高度結構。 -
These historians are like a botanist who, observing that several plants grow by their seed parting into two cotyledons, or seed - leaves, should insist that everything that grows only grows by parting into two leaves ; and that the palm - tree and the mushroom, and even the oak, when it spreads its branches in all directions in its mature growth, and has lost all semblance to its two seed - leaves, are departures from their theory of the true law of growth
這些史學家就像那樣的植物學家，他看見一些植物都是從雙子葉的種子里生長出來的，便堅持說，一切植物都要長成兩片葉子而那些已經長大的棕櫚蘑菇，甚至橡樹與兩片葉子毫無相似之處，他就認為這些植物偏離了理論。
