Do diverse landscapes provide for effective natural pest control in subtropical rice?
Journal of Applied Ecology, Volume 57, Issue 1, Page 170-180, January 2020., 2020 Our findings question the cost‐effectiveness of current chemical‐based pest management in farming, and highlight opportunities for more ecologically based pest management strategies based on the widespread activity of natural enemies. Pest damage and biocontrol, however, are largely independent from the landscape context, which might be due to the ...

Eyes on nature: Embedded vision cameras for terrestrial biodiversity monitoring
Methods in Ecology and Evolution, Volume 15, Issue 12, Page 2262-2275, December 2024.Abstract We need comprehensive information to manage and protect biodiversity in the face of global environmental challenges, and artificial intelligence is required to generate that information from vast amounts of biodiversity data. Currently, vision‐based monitoring methods are heterogenous; they poorly cover spatial and temporal dimensions, overly ...

GCB Bioenergy, Volume 16, Issue 1, January 2024.The use of biochar increased greenhouse gas (GHG) emissions but countered the harm caused by GHG emissions by considerable soil carbon sequestration resulting in a negative carbon footprint. Furthermore, the use of biochar lowered the proportion of CH4 and N2O, demonstrating that biochar usage has a considerable positive effect on GHG emissions ...

Shuitu Baochi Xuebao, 2016 以江汉平原连续水耕年限大于100 a（老稻田）和由旱耕改为水耕17 a（新稻田）的稻田为研究对象，通过测定土壤剖面基本理化性质和水力学参数，揭示了2种稻田土壤水分渗漏和保持特征差异。结果表明：（1）新稻田土壤的平均饱和导水率（Ks）为32.05 cm/d，显著高于老稻田（17.91 cm/d）。新、老稻田土壤Ks均表现为耕作层＞底土层＞犁底层，新稻田耕作层Ks分别为犁底层和底土层的6.3倍和5.7倍，老稻田耕作层Ks分别是犁底层和底土层的6.9倍和4.0倍。（2）老稻田土壤持水能力高于新稻田 ...

Ecological Compensation Evaluation of Yongding South Industrial Park in Fujian Province [PDF]
, 2013 运用生态系统服务功能价值法以及生态恢复成本法对福建省永定工业园南部园区开发的生态补偿费用进行了估算,以生态系统服务功能价值损失为上限、生态恢复成本为下限,经发展阶段系数、林地补偿系数、贴现率调整,得到生态补偿费用的下限为4 987.50万元/A,上限为56 760.25万元/A,指出通过利益相关者的协商博弈确定最终的生态补偿标准。Ecosystem services value assessment method and ecological restoration cost assessment ...

Testing AnnAGNPS for water quality modelling in the typical sub-watersheds in Jiulong River watershed [PDF]
, 2005 在中国东南丘陵山区一中尺度流域———九龙江流域选取4个土地利用方式不一的典型小流域,借助GIS和相关资料率定模型参数,并通过对2003年4月至9月各小流域出口降雨水质水量的同步监测,检验了连续分布式参数模型(AnnualizedAGriculturalNonPointSourceModel,AnnAGNPS)的适用性.研究结果表明,模型对于地表径流量的模拟能力好于对泥沙和营养盐的模拟,对总磷和泥沙输出的模拟结果表现出了较大的不确定性.

Shuitu Baochi Xuebao, 2006 在成都平原麦收后围绕免耕 麦秸覆盖还田栽种水稻的产量效应进行了研究,结果表明,(1)免耕处理较传统耕作水稻显著增产,主要是显著增加了单位面积有效穗数;(2)免耕 麦秸覆盖还田后,水稻产量增加,秸秆还田量与产量的关系符合多项式y=7238.6 0.0117x 2.12×10-5x2-1.49×10-9x3(R=0.988**),理论上还田麦秸以10 089 kg/hm2时水稻产量最高,此后开始下降;(3)与传统耕作比较,在水稻生长期,免耕明显加重了杂草的发生,但通过秸秆覆盖后可减少杂草发生 ...

Shuitu Baochi Xuebao, 2020 在浙东某地选择一污染农田，布设了秸秆还田、秸秆不还田、秸秆还田+石灰及秸秆不还田+石灰4个处理试验，进行了为期9年的土壤、秸秆、谷物、蔬菜等农产品中重金属动态监测。结果表明，污染农田中施用石灰可明显降低水稻秸秆和谷物及蔬菜中重金属的积累，但对土壤重金属含量影响不明显；施用石灰对水稻秸秆和谷物及蔬菜中重金属降低作用随试验时间逐渐减弱。与秸秆不还田比较，秸秆还田在短期内对土壤、水稻秸秆和蔬菜重金属积累的影响较小，但4~5年后秸秆不还田农田土壤镉、汞积累及水稻秸秆和蔬菜中镉、铅、汞积累明显低于秸秆还田农田 ...
