  1. The tiller - nodes of 6 species of rhizome grass, including leymus chinensis, hemarthriajaponica, arundinella hirta, calamagrostis epigeios, c. rigidula, hordeum brevisubulatum in songnen plain, can live at best for 2 to 5 years, and do 2 to 4 propagating generations which is the same as the age class of tiller in number. the age structure of population is an increasing model which the young tiller is more than the old at quantity and biomass. during the whole growing season, the age spectrum varies for each species

    松嫩平原，羊草、牛鞭草、野古草、拂子茅、硬拂子茅和野大麥等6種根莖型禾草種群的分蘗節最多可以存活2 5個年度，可以進行營養繁殖2 4個世代，分蘗株的齡級數與分蘗節營養繁殖的世代數相同，在種群分蘗株的數量和生物量上，生長季的各個時期均以幼齡分蘗株占較大比例，呈現為明顯的增長型年齡結構，各種類的年齡譜組成各異。
  2. The winter tiller is more than the spring tiller at quantity hi leymus chinensis, calamagrostis epigeios and c. rigidula population at the beginning growing season. it is an efficient strategy to increasing survival fitness and propagating potential for rhizome grass to grow many active and strong winter tillers

    生長季初期，羊草、拂子茅和硬拂子茅種群返青的分蘗株以冬性植株多於春性植株，冬性植株生活力旺盛、抗性強，形成冬性植株是根莖型禾草種群提高生存適合度，增強營養繁殖力的有效策略。
  3. The changing process of rhizome growing and the propagating process of population expanding supplement each other

    根莖自身的生長變化過程與種群的增長繁殖過程相輔相成。
  4. The age structure of rhizome is an increasing model at length and weight at the end of growing season

    在生長季末，種群中根莖在累計長度和重量上均為增長型年齡結構。
  5. Thus with citing these results we separatedly and thoroughly examined all possible dynamical manners of the changing of the ; populations when the species were developing under the function of catching efforts in three different areas departed by the size relation between the intrisic rates of the system and the values of the harvesting efforts. so we could give out - righter qualitative analysis to this system and the scope of catching efforts which make the species sustainable and the asymptotical properties of the corresponding system were also clear

    於是，本文在引用已有結論的基礎上，根據給定捕獲努力量與系統內稟增長率之間的大小關系分三部分考慮了在不同的捕獲努力量作用之下，種群發展過程中其個體數量變化可能出現的全部動力學行為，從而對系統給予了較完整全面的定性分析，求出了使生態系統持續發展的捕獲努力量的范圍及相應的系統的漸近性質
