基于城市搬迁地开展园林绿化项目建设是解决城市高密区可用绿化空间不足的重要途径.构建基于城市搬迁地的园林绿化项目效益评估指标体系,以上海世博公园为例,在公园建成后第8年(2018年),从环境、社会、经济和景观4个方面对该场地尺度绿化项目产生的多重效益进行系统性综合评价.结果表明:世博公园在应对气候变化、降低土壤污染、增加生物多样性以及园林植物景观的色彩与季相方面的单项效益较为突出;在水文调控、净化空气、缓解热岛效应、休闲游憩和可达性方面的单项效益仍具一定提升空间.世博公园的综合效益指数为70.98,评估结果为良,反映出这一基于城市搬迁地建设的公园绿地具有良好的可持续性,基本达到项目规划设计的预期效果.其中,评价结果从大到小依次为:景观效益(94.62)、环境效益(73.23)、社会效益(60.00)、经济效益(39.60).研究可为基于城市搬迁地的园林绿化项目建设成效评估提供借鉴,用于针对性地优化其单项效益和综合效益,从而促进此类项目的可持续发展.

在宁南山区的固原市原州区和彭阳县调查65个春玉米种植户的产量、施肥量及肥料种类等.结果 表明,该区域春玉米平均产量为9.4 t/hm2,80%的调查农户春玉米产量处在适中及偏低以下水平(<10.5 t/hm2).春玉米生产中N、P2O5、K2O养分的平均用量分别为353、253、370 kg/hm2,其中,化肥N、P2O5投入分别为314、175 kg/hm2,K2O全部来自有机肥.有机肥以牛粪为主(施用比例达89.2%),平均用量为25.6 t/hm2.氮、磷养分的平均偏生产力分别是31.6、61.1
依据文献资料以及农户调研数据,对北方玉米种植区的施肥现状和节肥潜力进行分析.调研数据表明,在当前北方玉米区平均玉米产量为9894 kg/hm2水平下,养分投入总量平均为512 kg/hm2,纯氮(N)投入总量为307 kg/hm2,纯磷(P2O5)投入总量为137 kg/hm2,纯钾(K2O)投入总量为68 kg/hm2.氮、磷、钾肥的偏生产力分别为33、78、135 kg/kg.当前农户施肥量总体超量,以最优化肥偏生产力为依据,推荐当前土壤条件下的北方玉米的平均氮、磷、钾施用量分别为193、86和60

桶混助剂是农药使用时与制剂产品搭配使用、现混现用的一种助剂.玉米田除草剂使用中合理添加桶混助剂能明显提高防治效果.介绍农药桶混助剂的定义、功能,并介绍玉米田化学除草基本情况,在此基础上分析桶混助剂对苗后茎叶处理除草剂、土壤处理除草剂的减施增效作用,展望桶混助剂未来的发展方向及市场前景.
Slope toe excavation strongly influences the stress balance of natural slopes and redistributes the stress of the slope body. Consequently, the sliding failure of toe-cut slopes is increasingly becoming more frequent, particularly in regions with persiste
In this study, dynamic centrifuge model tests were performed for sand slopes under different earthquake ground motions and slope angle to characterize the seismic performance of slopes. Four groups of tests under varying seismic input amplitude were condu

There is increasing evidence indicating that melts derived from subducted oceanic crust and sediments may have played a key role in building continental crust. This mechanism predicts that juvenile arc crust should have oxygen isotope characteristics rang
