论农业活动中的农民行为选择与保险需求

随着社会主义新农村建设的推进,农村改革不断深化,农民收入不断提高,农民对保险的认识逐步加深,对保险的有效需求也将逐步得到释放.农民对农业保险具有天然的需求,如能正确找出农业活动中的农民行为选择与保险需求的关系,将对农业保险发展起到积极的推动作用.     

Relationship of Land‐Use/Land‐Cover Patterns and Surface‐Water Quality in The Mullica River Basin1

Abstract: We describe relationships between pH, specific conductance, calcium, magnesium, chloride, sulfate, nitrogen, and phosphorus and land‐use patterns in the Mullica River basin, a major New Jersey Pinelands watershed, and determine the thresholds at which significant changes in water quality occur. Nonpoint sources are the main contributors of pollutants to surface waters in the basin. Using multiple regression and water‐quality data for 25 stream sites, we determine the percentage of variation in the water‐quality data explained by urban land and upland agriculture and evaluate whether the proximity of these land uses influences water‐quality/land‐use relationships. We use a second, independently collected water‐quality dataset to validate the statistical models. The multiple‐regression results indicate that water‐quality degradation in the study area is associated with basin‐wide upland land uses, which are generally good predictors of water‐quality conditions, and that both urban land and upland agriculture must be included in models to more fully describe the relationship between watershed disturbance and water quality. Including the proximity of land uses did not improve the relationship between land use and water quality. Ten‐percent altered‐land cover in a basin represents the threshold at which a significant deviation from reference‐site water‐quality conditions occurs in the Mullica River basin.

清江水布垭水库农村移民安置区环境容量研究

清江是长江流出三峡之后的第一条大支流,发源于鄂西利川市,自西向东流经湖北省的１０个县（市）,于宜都市注入长江,在清江建设水布垭水电站是“流域,梯极,滚动,综合”开发利用清江水利资源的重要决策,将促进区域经济的发展。水布垭水库淹没涉及巴东,鹤峰,建始,宣恩,恩施５县（市）的陆地面积５５．４ｋｍ＾２,其中耕园地１１４７．８ｈｍ＾２。     

白色农业:21世纪养活16亿中国人的重大工程

白色农业是我国新的农业科技革命的重要组成部分。发展白色农业既可以满足我国２１ 世纪对食品数量增加、质量改善和安全性的需求,又能有效地提高动、植物资源利用率,改善和保护生态环境。白色农业是我国２１ 世纪养活１６ 亿人的强有力保证。     

生物炭在新疆棉田的应用效果研究

农业是新疆经济和社会的基础,维系着全疆广大农牧民的生计,也关系到民族团结、边疆稳定和各族人民生活水平。寻求新技术提高绿洲农业生产力是新时期新疆经济和社会发展的要求。我们将小麦秸秆生物炭应用于喀什绿洲的灌淤土,研究了其对土壤pH和土壤水分的影响以及对棉花生长和产量的促进作用。结果显示,10%生物炭施用量可以倍增田间持水量,并提高土壤pH值0.36。但后一作用会随土壤灌溉和淋滤作用的增加而降低;在混合施用方式下,生物炭显著提高棉花产量,5%的施用量提高皮棉产量26%。这种增产效果产生的原因是生物炭的施用增加了土壤的营养成分和供水能力,从而增强了植株的株高、果枝数和单株铃数等。但条施方式对棉花的增产效果不显著,其施用过程会伤及作物根系和/或纯生物炭的高碱性影响植株的生理作用,从而造成棉株的枯萎、迟滞作物的生长。上述结果表明生物炭技术是提高绿洲农业生产力很有潜力的一条途径,但施用方式是一个很重要的影响因素。本研究结果不仅可以直接指导新疆绿洲的棉花生产,还可以为我国北方广大干旱区农业生产和管理提供借鉴。
