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
本研究以重慶市的南川金佛山(自然保護區) 、黔江武陵山(國家重點退耕還林示範縣,森林覆蓋率50以上)和北碚中梁山(遭人為破壞嚴重)典型巖溶區為對象,選擇了幾種重要的利用方式,包括林地、果園、耕地、棄耕地和灌草坡,採用野外巖溶生態調查和室內試驗測量分析相結合的方法,以不同
土地利用方式巖溶
土壤肥力為重點,對不同
土地利用方式
土壤肥力特徵進行量化分析,找出巖溶
土壤肥力差異的主要方面及其根本原因,論文主要從
土壤剖面物理退化指標(有效
土層厚度、有機質層厚度、質地、團聚體、水分含量等) ,化學肥力退化指標(有機質、全n 、全p 、全k 、堿解n 、速效p和速效k等) ,樣地
土壤微生物指標(細菌、
真菌、放線菌數量及總量)以及樣地
土壤種子庫植物群落多樣性等4個方面對重慶典型巖溶區的
土壤肥力特徵進行了較為詳細的分析研究,為巖溶地區士壤資源的合理利用及結構的調控管理提供依據。
1. ecological effects of long - term organophasphate pesticides contamination on soil microflora the long - term effects of organophosphate pesticides contamination on soil microflora were investigated in the present study. little difference in total counts of bacteria, actinomycetes and fungi was observed between the contaminated and the non - contaminated soil. compared with the control there were a slight decrease in total counts of free - living nitrogen - fixer and denitrifying bacteria and a significant increase in those of ammonifying and ammonia - oxidizing and nitrifying _ bacteria in the methylparathion contaminated soil
一、甲基對硫磷長期污染對
土壤微生物的生態學效應研究了有機磷農藥甲基對硫磷長期污染對
土壤微生物的影響,實驗表明:
土壤細菌、放線菌、
真菌總的數量影響不大;自生固氮菌和反硝化細菌數量減少;氨化細菌、亞硝化細菌、硝化細菌的數量在污染
土壤中卻有所增加;與對照
土壤相比,污染
土壤呼吸作用下降了29 . 93 ;氨化作用和硝化作用強度得到增強。
