The germplasm of medicinal plant is the key in the course of plant medicine producing. lt has direct relation to cultivation of medicinal plant and the quality of crude drug. at present, there is a large - scape area in the cultivation of dioscorea plant with high diogenin, but for neglecting the unstability of germplasm and breeding of valuable cultivars, the quality is not enough to use as crude drug, which lead to supply falling short of demand. therefore, keeping stability of good germplasm, as well as breeding new dioscorea cultivars with high diogenin and yield is urgent and valuable to study
在我國，盾葉薯蕷和穿龍薯蕷等因為較高的薯蕷皂甙元含量，都有很大的栽培面積，但作為原料藥其產量和質量並未達到植物藥生產所需，導致市場供需矛盾十分突出，就是因為只簡單地將野生資源挖回來種植，忽略了種質的不穩定和有栽培價值的品種的培育，因而保持優良種質的穩定性和培育高含量、高產量的薯蕷新品種是一個緊迫而又有價值的研究課題。 -
In part one, the general of reclamation of arable land for reforestation : basing on resulting lots of data, author referred to many measures taken by america and china in the reclamation of arable land for reforestation and took the comparison, which concluded the following : china does not take the ways that the developed countries firstly destroyed before protection ; carrying out the reclamation of arable land for reforestation step and step is the important step which improves the reasonlesss utilization of land ; because of the weak economic base in the reclamation of arable land for reforestation of china and the low rate of labor, we should enlarge the content of science and technology, improve per yield of the remaining cultivated land and solve the self - sufficiency of grain, meanwhile the government should strengthen the transfer of remaining labor, adjust the industrial construction and lead the construction of small cities and towns ; the implement of reclamation of arable land for reforestation does not leave the support of the government ; we should carry out the reclamation of arable land for reforestation according to law ; the reclamation of arable land for reforestation does not be seen the effort in the short time, we should insist in a long time. which can have the result
本論文共分八個部分：第一部分退耕還林概況：筆者在查閱大量資料的基礎上，參閱美國與中國的退耕還林過程中所採取的各項措施並進行比較，得出了以下結論：中國不能重走發達國家先破壞后保護的道路；有計劃、有步驟地實施退耕還林是改善不合理土地利用現象的有力舉措；中國退耕還林經濟基礎較為薄弱，農業勞動生產率低，退耕還林后，必須加大科技含量，提高剩餘耕地的單產，解決糧食自給問題，同時，政府應加強剩餘勞動力轉移，產業結構調整及小城鎮建設的引導；退耕還林的實施仍離不開政府的扶持；依法退耕還林；退耕還林不是在短期內能見到效果的，長期堅持必有成效。該部分最後論述了目前國內退耕還林工程政策、管理方面的現狀及其存在哪些問題尚待改進或繼續深入研究，並需要進一步完善。第二部分退耕還林背景分析：針對我國目前生態環境建設中的退耕還林工程，就其產生的根源從社會經濟背景、生態環境背景及西部大開發三個角度進行了全面、系統的分析。 -
This paper reaches a conclusion that the three methods of term structure estimation lead to the difference of the pricing of irdp and that the cubic interpolation is the best method when these methods are applied to construction of zero - yield curve and evaluation of coup bond, zero - bond option and interest rate swap
