On the base of serious summarizing the experience of more than 20 pilot villages of the all city during the past 7 years, twice villages surveys in large scale in 1999 and 2001 ( including over 200 villages ) and thirteen pilot villages in the project of rural development by technology and education project in beijing in 2002, generalizing experience on how to develop village economy and rural development by technology and education project entirely, extrapolating the operating mechanism, management system and village development pattern in how to rely on technology to train rural elites and boom village economy especially. thereby, representing the conception, goal and operating clue of village economy and rural development by technology and education project for 21st century in beijing in detail. it is the first time to represent four operating thesis of rural development by technology and education project for 21st century in china systematically : system thesis of village productive forces ( inside ) ; regional actinoid thesis in village ( outside ), operating thesis for origin, bank and fluid, and the thesis of biology balancing and limited factors

結歸納了7年來北京市如何依靠科技、培育鄉土人才、促進村域經濟發展的科教興村的管理體系、運作模式、村級發展模式;在此基礎上,詳細闡述了21世紀北京市科教興村的概念、目標和工作思路;並在國內首次較系統地、深入地闡述了21世紀科教興村的四大運行理論基礎:村域生產力系統理論(對內) 、村域
區域經濟發展輻射理論(對外) 、 「源、庫、流」運轉學說和「生態平衡理論和限制因子學說」 。
The results indicated that, the total quanlity of major soil microbes declined, of which the minesoils was decreased by 68. 43 % ~ 80. 32 % in the top soil ( 0 - 20cm ) compared with that of the non - minesoils. the proportion of bacteria and actinomyces in the amount microbes decreased, while that of fungi not obviously changed

They are jinfo mountain in nanchuan county ( natural protection section ), wuling mountain in qianjiang county ( national emphases forest demonstration county which forest cover rate is beyond 50 % ) and zhongliang mountain in beibei county ( artificial destruction is very grave ). some main land use patterns i. e. woodland, garden, infield, abandon infield, shrub and grassplot are selected in those three sample sites. four aspects on soil fertility index of karst environment under different land use patterns in these three sample sites, are revealed in this paper, by using the field test, indoor measure and analysis, outdoor experiment and field investigation, and the knowledge and technique of soil, ecology, physics and chemistry etc. they are physical characteristic ( effective soil thickness, organic layer thickness, soil texture, water - stable aggregate and soil water etc. ), chemical fertility ( organism, omni - n, omni - p, omni - k, alkali - nitrogen, available p, available k and rapid available k etc. ), soil animalcule ( bacteria, fungi, actinomyces and their grosses ) and soil - seed - pool ( plant community diversity index ) in karst ecosystem
