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

The total rna was isolated from pokeweed ( phytolacca americana ) leaves using the method of guanidine isothiocyante and used as template to amplify the total length and deleted mutant pokeweed antiviral protein ( pap ) gene by rt - pcr and then the pap gene was cloned into pgem - t vector. the sequencing results showed that pap gene had 99. 9 % identity comparing with the pap gene nucleotide sequence reported by lin et al ( 1991 ). the iptg - inducible expression vector containing the pap gene was constructed and transferred into e. coli bl21 ( de3 ) - plyss
