于2005～2007年3～7月采用在试验样地中添加巢位(悬挂巢箱)与对照样地比较的方法,探讨悬挂巢箱是否影响天然洞的入住率,并为次级洞巢鸟类提供巢位资源,进而增加繁殖种群的数量。结果发现,无论是试验样地还是对照样地,总的入住数量年间差异不显著,种类间差异显著;天然洞之间(无论是否悬挂巢箱)的入住率差异不显著;人工巢箱与试验样地的天然洞之间的入住率差异极显著;人工巢箱与对照样地的天然洞入住率差异极显著。结果表明,人工巢箱的添加为次级洞巢鸟提供了巢位资源,大大地提高了入住率;人工巢箱的悬挂并未影响天然洞的入住率,试验样地与对照样地的天然洞的入住率没有显著区别,表明适合鸟类入住的天然洞巢位资源在次生阔叶林中,处于稳定且饱和状态。所以悬挂巢箱不影响天然洞的入住率,而且为次级洞巢鸟类补充了巢位资源,因此增加了繁殖种群的数量。

为了确定大山雀对巢箱颜色是否能够识别和对繁殖功效的影响,以利于更好的进行保护,于2007—2010年3—7月,在吉林省左家自然保护区,通过悬挂黑、蓝、绿、白和红色巢箱,对大山雀的入住状况和繁殖参数进行了调查和分析。结果显示:2007、2008、2010年红色巢箱的入住率最高,2009年低于平均值;窝卵数除2010年红色巢箱组略低于其它颜色组平均值外,其它年份略高于其它组,而各年份的出飞数红色组均高于其它组。将其它组的合并均值与红色组进行了方差分析,结果表明,窝卵数之间无显著差异,而出飞数之间则有显著差异(F=17.65,df=1,P=0.04),表明红色组的出飞数高于其他组的平均值。

China has sought to address water pollution in the last decade by introducing a wide range of laws and regulations(Table S1), which led to nationwide water quality improvement [1]. However, recent quantitative assessment of progress toward Sustainable Development Goals (SDGs) in China suggests that some SDGs underpinning goals for water pollution and biodiversity have not been met [2].
