Shuitu Baochi Xuebao[目的] 为了解根河流域湿地时空变化情况,明晰气候变化和土地利用变化对湿地景观格局的影响。[方法] 过分析根河流域1990—2019年间的湿地范围变化,再结合期间的气候变化状况来探究流域内湿地景观格局变化的驱动因素。[结果] 30年,根河流域湿地面积减少31.89%,斑块数量增加3.74%,景观破碎度指数增加4.48,流域湿地面积总体退化显著,流域湿地斑块数量总体有所增多。1990—2004年流域湿地呈现出显著退化趋势(p＜0.05),湿地面积与年降水量存在显著正相关关系 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2011 【目的】探讨第3天（D3）慢速冷冻胚胎解冻后当天移植（Embryo Transfer, ET）和体外培养1 d后ET在自然周期和人工周期中对临床结局的影响。【方法】回顾性分析本中心2009年1月至2010年12月期间的解冻胚胎数≥1，且≤3的552个卵裂期冷冻胚胎TET周期的临床结果，根据解冻后体外培养时间分为A组（当天ET）和B组（培养1 d后ET），这两个组再分为自然周期组和人工周期组。【结果】D3冷冻胚胎在自然周期和人工周期，A、B两组女方年龄、平均移植胚胎数、胚胎评分以及妊娠率均没有统计学意义 ...
