The results shows that the community richness, species diversity indices and evenness of tree layer and shrub layer share the same order, of which is higher in pure limestone region than that of in pure dolomite region, but it reverse in herb layer ; the coefficient of similarity is considerably low between all plots, while species turnover rate is quite high among the plots and is higher in dolomite region than that of in limestone ; in different karst regions, karst processing leads to niches diversity characterized by special morphologies and special element geochamical features, and therefore affect the dynamic and features of plant communities
我們在最有代表性之一的貴州茂蘭喀斯特森林保護區選取純灰巖和純白雲巖兩種巖性的喀斯特環境，對其元素地球化學特徵及其中原生性植物群落的相異性和物種多樣性進行了對比，結果發現：不同巖性區域多樣性：喬木層和灌木層為純灰巖區純白雲巖區，草本層為純白雲巖區純灰巖區，總體上純灰巖區的高於純白雲巖區的；各樣地間的相似性系數都很低，相同巖性類型內的明顯高於不同巖性類型之間的相似度；物種周轉率高，且白雲巖區高於石灰巖區，種類組成差異明顯；喀斯特區可溶巖地球化學背景通過喀斯特作用導致特殊的地形條件與元素地球化學特徵，並引起局部小生境的分異從而影響植物群落特徵。The paper also conducted cost and benefit analysis that indicates the protection cost is very much higher in ipr protection in agriculture in china as compared with other countries such as the us and other western countries, this is a very important restricting factor for the patent and pvp application in china. besides, the paper also discussed the possibilities of the unified system like pct and upov for ipr applications to minimize the cost of application and maintainence. with support of survey data and developed models, the papers conclude with the priority area for ipr protection in agriculture in order is as follows : pvp, patent, trade secret, and trade marks
同時，在大量檢索和設計調查問卷的基礎上，對我國農業知識產權保護的成本和效益進行理論分析，在對比其他國家專利和新品種保護成本的基礎上，分析出我國申請農業知識產權保護的成本和被侵權后的司法訴訟成本過高，影響了我國農業知識產權的申請和保護；此外，文章還就建立類似專利合作條約（ pct ）性質的國際植物新品種保護公約，以期在多國專利同時申請方面實現帕累托最優原則進行了理論探討，在此基礎上，文章進一步對比分析實施農業知識產權保護規則對我國農業技術貿易特別是國外直接投資可能帶來的影響進行，結果表明，強化農業知識產權保護，發展中國家會增加農業技術和產品的進口，發展中的大國更是如此；文章在調查問卷的基礎上提出了我國農業知識產權方面存在的問題和今後農業知識產權保護的目標體系和優先領域，農業知識產權保護的優先順序依次為：新品種、專利、商業秘密、商標和原產地。Nitric oxide can be produced in plant cells via animal no synthase ( nos ) or nitrate reductases and through nonenzymatic reactions
摘要植物體可以通過依賴于類似哺乳動物的一氧化氮合成酶或硝酸還原酶的酶促合成途徑和非酶促合成途徑產生一氧化氮。A review with 11 references is given on the establishing principle and method of normal reference value of elements in human hair and blood including the definition, determination, expression, transference, and significance of reference value
