Abstract Accurate forecast of future container throughput of a port is very important for its con struction, upgrading, and operation management. This study proposes a transfer forecasting model guided by discrete particle swarm optimization algorithm （TF-DPSO）. It firstly transfers some related time series in source domain to assist in modeling the target time series by transfer learning technique, and then constructs the forecasting model by a pattern matching method called analog complexing. Finally, the discrete particle swarm optimization algorithm is introduced to find the optimal match between the two important parameters in TF-DPSO. The container throughput time series of two im portant ports in China, Shanghai Port and Ningbo Port are used for empirical analysis, and the results show the effectiveness of the proposed model.

Journal of Integrative Agriculture 2019年第3期18卷 563-570页

作者： HUANG Min FAN Long JIANG Li-geng YANG Shu-ying ZOU Ying-bin Norman Uphoff Southern Regional Collaborative Innovation Center for Grain and Oil Crops(CICGO) Hunan Agricultural UniversityChangsha 410128P.R.China international Programs-College of Agriculture and Life sciences(IP-CALS) Cornell UniversityIthaca 14853USA Key Laboratory of Crop Cultivation and Farming System Guangxi UniversityNanning 530004P.R.China

Biochar is considered as a beneficial soil amendment for crop production. However, limited information is available on the effects of continuous applications of biochar on rice. In this study, a fixed field experiment was conducted in the early and late rice-growing seasons from 2015 to 2017. Grain yield and yield attributes with a widely-grown rice cultivar Zhongzao 39 were compared, with and without applications of biochar in each season. The results showed that grain yield initially decreased with biochar applications in the first three seasons due to decreases in grain weight and harvest index. Although there were further relative decreases in grain weight and harvest index for rice that was supplied with biochar in the fourth to sixth seasons, grain yield was increased(by 4–10%) because of increases in sink size(spikelets per m2) and total biomass. The increased sink size in rice whose soil had been supplied with biochar in the fourth to sixth seasons was achieved by increasing panicle size(spikelets per panicle) or number of panicles, or both. Our study suggests that the positive effects of biochar application on rice yield and yield attributes depend on the duration of biochar application. Further investigations are needed to determine what are the soil and physiological processes for producing yield responses associated with ongoing applications of biochar. Also, it should be evaluated the performance of biochar application combined with other management practices, especially those can increase the grain weight and harvest index in rice production.

污染耕地土壤重金属元素含量分布特征提取涉及不同地理区域和土壤类型,获取大范围土壤重金属元素含量数据难度大,因此提出基于地理信息的污染耕地土壤重金属元素含量分布特征提取方法。以某市为例,采集该市污染耕地土壤与植物样本,利用色谱仪测定样本内重金属元素含量,并采用地理信息系统获取辅助信息,得到大范围土壤重金属元素含量数据,结合投影寻踪函数实现土壤重金属元素含量分布特征提取。试验结果表明,该方法可有效提取出该市污染耕地的重金属元素类别和含量,且地理信息系统生成的分布特征可视化效果较好,特征提取精度高。
