因此，加快退耕還林還草，調整土地利用結構和產業結構，已成為實現山川秀美工程和可持續發展戰略的必經之路。論文以解決陜北地區的收入問題，植被問題以及糧食產量問題為出發點，首先從理論上分析了包絡分析方法在陜北地區退耕還林（草）中運用的可行性，然後結合陜北地區目前的實際情況，綜合分析出影響陜北地區退耕還林（草）的關鍵的七個因素作為輸入指標：水利水保設施投入，農作物投入，經濟林種支出，防護林支出，其它經濟作物，草類支出，畜牧業投入；以退耕還林所要解決的最終問題作為輸出指標： gdp收入、農民人均純收入、水土流失減少量、牧業總產值、糧食產量、林業總產值、其他經濟作物總產值。將各指標所對應的數據代入模型后，通過分析求解得出非有效的決策單元，再運用包絡分析方法的一些基本原理對非有效的決策單元進行調整，由此所得的數據對陜北地區的實際投入具有很好的指導意義。 -

Rubber tree ( hevea brasiliensis ) is an important economic woody - crop in tropical areas. its latex is the unique source of crude rubber used in current industry. because of its special and important use, the rubber tree has been extensively planted in tropical areas. increase production is always the main target in rubber tree cultivation. since the ethrel was applied in increasing latex production in 1968 for the first time as a chemical stimulant, not only the latex production had been increased largely, but also a new set of rubber tapping system had been established, leading to a series of economic benefit. owing to ethrel " s extensive application, its side effects had been found more and more obviously, such as tapping dry, speeding up senescence, shortening the life span of rubber tree etc. in order to overcome the side effects and increase production more availably, for a long time, people had carried out lots of research work on cell level, membrane level, physiology and biochemistry of laticifer contents. but the mech anism why ethrel increased latex production was not yet understood completely. this study had cloned the ethylene receptor gene ( efrl ) from rubber tree, and researched the relationship between etrl expression in laticifers and ethrel stimulation on transcription level and protein translation level. the results were as follows : 1
但是，由於乙烯利應用的普及，乙烯利刺激割膠引起橡膠樹發生死皮病及加速膠樹衰老，縮短膠樹壽命等副作用也越來越明顯。為了克服這些副作用，使乙烯利能更有效地刺激增產，長期以來，人們在細胞水平、膜水平和乳管細胞內含物的生理生化層面上進行了大量的研究，但仍未完全了解乙烯對膠樹的作用機制。本研究從分子水平入手，克隆橡膠樹的乙烯受體基因（ etr1 ） ，並在轉錄水平和蛋白質翻譯水平上研究etr1基因在乳管細胞中的表達及與乙烯刺激的關系，取得了以下結果： 1 -
