[Objective] This study was to investigate the genetic parameters on reproduction performances of China Yorkshire line SII,. [Method] Using China Yorkshire line SII, as experimental animal, its genetic parameters on reproduction performance, such as total number of born （TNB）, the alive number of born （ANB）, the litter weight of born （LWB） and the litter weight at age of 21 days （/W21 ） , were estimated by using the DFREML method of multi-traits animal model. [Result] The heritability estimates of TNB, ANB, LWB and LW21 were 0.11,0.19, 0.14 and 0.05, respectively; and the genetic correlations between the traits as TNB/ANB, TNB/LWB, TNB/LW21, ANB/LWB, ANB/LW21, LWB/LW21 were 0.91, 0.76, 0.65, 0.85, 0.59 and 0.38, respectively. [ Conclusion] Main genetic parameters of reproduction traits in China Yorkshire line all, have all reached or even exceeded the requirements of breeding.

基于"前向联系增加值出口"方法,测算了1995-2011年中国服务业细分产业层面及按要素密集度特征分类层面的显性比较优势指数(RCA_F),并同基于"总出口"1的比较优势指数(RCA)进行了比较。研究发现,中国在全球价值链分工中,比较优势集中在资本密集型服务业领域,且实现了比较劣势向比较优势的转变;劳动、知识密集型服务业及健康教育公共服务均尚未取得比较优势,但是有迹象表明三个领域的比较劣势有改善的趋势。与基于前向联系增加值出口核算结果相比,基于总出口核算结果"高估"了劳动密集型产业的比较优势,其中对建筑业和零售贸易两个部门的估计偏差最大;同时,在资本、知识密集型两个领域存在不同程度的"低估"现象。

从古籍包括正史、地方志、家谱、碑志等对桐庐县翙岗村的水利遗迹谷井和上澳的建造时间和主事者进行考证,得出:谷井为明代李盛开掘,时间在正德七年(1512)之前很近的时间内;挖掘上澳“引向田野”的支线而不是兴建上澳的主事人为明代李棐,该时间与李盛开掘谷井的时间相近。古村遗迹的研究要综合利用各种古籍,将研究提升至“于史有据”的程度;而在利用古籍时,要对其辨伪、分析,才能得出更为准确、科学的结论。以古籍切入古村遗迹研究,与中共中央和国务院颁发了《关于推进新时代古籍工作的意见》中提及的“传承中华农耕文明优秀成果,服务乡村振兴”相符,这正是古籍研究的时代价值。

自《珠江三角洲地区改革发展规划纲要》(2008～2020年)发布以来,珠江三角洲地区发展问题成为社会各界热议的焦点。从人文地理学视角,对《纲要》进行深入解读。第一,珠江三角洲地区发展步入深水港时期,机遇和挑战并存,《纲要》对于珠江三角洲地区未来发展是一种及时的强心剂。第二,改革和开放是解决目前珠江三角洲地区面临诸多问题的关键,是开拓珠江三角洲未来的最主要凭借。第三,从珠江三角洲地区产业发展情况看,区域发展观的树立是构建现代产业体系的核心要务。第四,在分析完全市场条件下的经济一体化发展策略利弊基础上,提出政府引导型发展模式。其核心思想在于政府部门要尽力规避完全市场条件下一体化策略的诸多弊端,要把发展权力下放到基层,让其拥有地方发展自主权,以增进地方经济与社会文化的多样性。
