[目的/意义]为探究并表达环境因素对黄花各器官生长发育、形态结构和产量的影响,提出一种基于源库关系的黄花植株三维动态生长及产量模拟模型。[方法]以大同地区黄花主要栽培种植品种大同黄花为研究材料,采集黄花叶片、花葶、花蕾等形态数据和叶片光合生理参数,利用功能-结构植物模型(Functional-Structural Plant Model,FSPM)平台的三维建模技术,建立基于云量的室外地表太阳辐射模型及适配黄花的光合作用模型,同时基于黄花源库关系建立黄花光合产物碳分配模型,利用β生长函数构建黄花各器官生长模拟模型,计算黄花生长期内逐日形态数据,最终实现黄花植株三维动态生长及产量模拟。[结果和讨论]采用实测数据对模型进行检验。结果显示,室外地表太阳辐射实测值和模拟值R2为0.87;剩余标准差(Root Mean Squared Error,RMSE)为28.52 W/m^(2),黄花各器官模拟模型实测值和预测值R^(2)为0.896~0.984,RMSE为1.4~17.7 cm;平均花蕾产量模拟R^(2)为0.880,RMSE为0.5 g;整体F值为82.244~1168.533,Sig.值均小于显著水平0.05,表明上述模型拟合度和显著性较好。[结论]模型能够准确地表现黄花植株在3个主要生长时期的生长规律和形态特征,模拟结果与实际情况相符合,表现出较高的可信度。因此,本模型具有理想的模拟效果,足以满足精细农业领域的研究需求。

FSPM-P： towards a general functional-structural plant model for robust and comprehensive model development

Frontiers of Computer Science 2016年第6期10卷 1103-1117页

In the last decade, functional-structural plant modelling （FSPM） has become a more widely accepted paradigm in crop and tree production, as 3D models for the most important crops have been proposed. Given the wider portfolio of available models, it is now appropriate to enter the next level in FSPM development, by introducing more efficient methods for model development. This includes the consideration of model reuse （by modularisafion）, combination and comparison, and the enhancement of existing mod- els. To facilitate this process, standards for design and communication need to be defined and established. We present a first step towards an efficient and general, i.e., not speciesspecific FSPM, presently restricted to annual or bi-annual plants, but with the potential for extension and further generalization. Model structure is hierarchical and object-oriented, with plant organs being the base-level objects and plant individual and canopy the higher-level objects. Modules for the majority of physiological processes are incorporated, more than in other platforms that have a similar aim （e.g., photosynthesis, organ formation and growth）. Simulation runs with several general parameter sets adopted from the literature show that the present prototype was able to reproduce a plausible output range for different crops （rapeseed, barley, etc.） in terms of both the dynamics and final values （at harvest time） of model state variables such as assimilate production, organ biomass, leaf area and architecture.

Anemia and long-term outcome in adjuvant and neoadjuvant radiochemotherapy of stage Ⅱ and Ⅲ rectal adenocarcinoma:The Freiburg experience(1989-2002)

World Journal of Gastroenterology 2006年第12期12卷 1849-1858页

AIM： To evaluate the long-term outcome of standard 5-FU based adjuvant or neoadjuvant radiochemotherapy and to identify the predictive factors, especially anemia before and after radiotherapy as well as hemoglobin increase or decrease during radiotherapy. METHODS： Two hundred and eighty-six patients with Union International Contre Cancer （UICC） stage Ⅱ and Ⅲ rectal adenocarcinomas, who underwent resection by conventional surgical techniques （low anterior or abdominoperineal resection）, received either postoperative （n = 233） or preoperative （n = 53） radiochemotherapy from January 1989 until July 2002. Overall survival （OAS）, cancer-specific survival （CSS）, disease-free survival （DFS）, local-relapse-free （LRS） and distant-relapse-free survival （DRS） were evaluated using Kaplan-Meier, Log-rank test and Cox＇s proportional hazards as statistical methods. Multivariate analysis was used to identify prognostic factors. Median follow-up time was 8 years. RESULTS： Anemia before radiochemotherapy was an independent prognostic factor for improved DFS （risk ratio 0.76, P= 0.04） as well as stage, grading, R status （free radial margins）, type of surgery, carcinoembryonic antigen （CEA） levels, and gender. The univariate analysis revealed that anemia was associated with impaired LRS（better local control） but with improved DFS. In contrast, hemoglobin decrease during radiotherapy was an independent risk factor for DFS （risk ratio 1.97, P= 0.04）. During radiotherapy, only 30.8% of R0-resected patients suffered from hemoglobin decrease compared to 55.6% if R1/2 resection was performed （P= 0.04）. The 5-year OAS, CSS, DFS, LRS and DRS were 47.0%, 60.0%, 41.4%, 67.2%, and 84.3%, respectively. Significant differences between preoperative and postoperative radiochemotherapy were not found. CONCLUSION ： Anemia before radiochemotherapy and hemoglobin decrease during radiotherapy have no predictive value for the outcome of rectal cancer. Stage, grading, R status （free radial margins）, t
