[目的]在建立健全草原风险管理体系,保障草原生态安全和稳定草原畜牧业生产的背景下,草原保险的作用更加凸显。草原风险评估和区划作为草原保险设计的前提和基础,其准确性直接决定着草原保险条款的合理性及科学性。[方法]文章利用半定量化因果关系矩阵法、HP滤波模型、多种聚类分析法和单因素方差分析法。[结果]可将锡林郭勒草原分为低、中、高和极高4个风险区,各风险区间的差异显著,其中,低风险区呈现出致灾因子危险性低、承灾体脆弱性低和防灾减灾能力强的显著特点;中风险区呈现出承灾体暴露性水平高,但致灾因子危险性处于中等水平的显著特点;高风险区呈现出致灾因子危险性高,防灾减灾能力处于中等水平的典型特征;极高风险区呈现出承灾体脆弱性水平高,防灾减灾能力弱的典型特征。[结论]在厘定草原保险费率时,应考虑多种风险间的交互作用,构建合理的草原风险区划图。

BACKGROUND Esophageal carcinoma presents as 2 types,esophageal adenocarcinoma(EAC)and esophageal squamous cell carcinoma(ESCC)with the frequency of both changing in the United States(US).AIM To investigate EAC/ESCC incidence time trends among the 3 main US racial groups and investigate trends in US EAC survival by *** Twenty-five years(1992-2016)of data from SEER 13 program was analyzed to compare incidence trends in EAC and ESCC between non-Hispanic whites(nHW),non-Hispanic Blacks(nHB)and Hispanics(Hisp)using SEERStat®.In addition,SEER 18 data,from 1975-2015,on EAC in the US was analyzed to evaluate racial disparities in incidence and survival using SEERStat®and Ederer II *** In the 3 major US ethnic groups,age-adjusted incidence of ESCC has declined while EAC has continued to rise from *** note,in Hisp,the EAC incidence rate increased while ESCC decreased from 1992 to 2016,resulting in EAC as the predominant esophageal cancer subtype in this group since 2011,joining ***,although ESCC remains the predominant tumor in nHB,the difference between ESCC and EAC has narrowed dramatically over 25 *** survival probabilities were worse in all minority groups compared to *** Hisp have joined nHW as US ethnic groups more likely to have EAC than *** note,EAC incidence in nHB is increasing at the highest rate *** lower EAC incidence in all minority groups compared to nHW,these populations have decreased survival compared to nHW.

Evaluating the Intercropping of Millet with Cowpea for Forage Yield and Quality

引用

American Journal of Plant Sciences 2018年第9期9卷 1781-1793页

A field study was scheduled to estimate the impact of intercropping of pearl millet with cowpea on forage yield and quality at Agronomy Research Farm, University of Agriculture, Faisalabad. It was done in kharif season 2016. Randomized complete block design was used to conduct this experiment. It has three replications. The size of net plot is 3.6 m × 6 m. It comprised of five treatments (T1 = one row of millet alternating with one row of cowpea (1M:1C), T2 = two rows of millet alternating with one row of cowpea (2M:1C), T3 = one row of millet alternating with two rows of cowpea (1M:2C), T4 = sole millet, T5 = sole cowpea). We found that intercropping significantly effected the yield and quality of forage. Intercropping system had significant effects on nutritive value of forage crop. Within various treatments of intercropping, it is evident that treatment T2 (two rows of millet alternating with one row of cowpea) gives maximum total dry matter yield (9.68 t ha-1). It was then tracked by treatment T1 (one row of millet alternating with one row of cowpea) and treatment T3 (one row of millet alternating with two rows of cowpea) producing dry matter yield (9.07 t ha-1 and 8.33 t ha-1, respectively). Based on high grain and suitable environmental condition, intercrop productivity compared to sole crop could be selected for improving the productivity of millet/cowpea mixture in the Punjab.
