Vocational colleges to build a “posts, courses, competitions and certificates” integrated education mode is an important means and approach for our country’s vocational education to cultivate high-quality technical and skilled talents in the new era. However, there are still problems such as insufficient role of parttime teachers in enterprises and mere formalities in teacher training in higher vocational colleges under the current education mode of “posts, courses, competitions and certificates”. To solve the above problems, it is necessary to continuously deepen the integration of industries and education, the cooperation of schools and enterprises, jointly promote the teachers’ training and training system, strengthen the teachers’ skills competition system, and certify the teacher’s hierarchical classification evaluation system, highlight the combination of “double-qualified” teachers’ individual growth and “double-qualified” teaching team building,focus on improving teachers’ ideological and political quality and moral quality, improve teachers’ education and teaching ability and practical skills, and create a teaching team that meets the requirements of cultivating talents by means of integrating “posts, courses, competitions and certificates”.

以内蒙古包头市南海湿地土壤理化性质为试材,采用野外取样与室内试验分析相结合的方法,研究了内蒙古包头市南海湿地不同季节(春季、夏季和秋季)土壤养分分布特征及其影响因素,以期为该区域土壤质量评价提供参考依据.结果表明:1)包头市南海湿地土壤理化指标均符合正态分布.其中,全盐量、有机质、全氮和全磷均具有强变异性,说明不同季节这4种指标的变异程度较大.2)不同季节平均土壤有机质、全氮、全磷和全钾含量分别为 9.59～18.80、0.36～0.70、0.67～1.07、16.21～22.39 g·kg-1.3)各土层土壤全盐量、有机质、全氮和全磷随季节呈先增后减的变化趋势,土壤pH、全钾随季节呈逐渐递减的变化趋势.4)在同一季节,土壤容重、土壤含水量、土壤总孔隙度、土壤毛管孔隙度和土壤非毛管孔隙度随着土层深度增加变化各异.土壤全盐量、有机质、全氮和全磷随土层深度增加整体呈逐渐降低的趋势.5)冗余分析结果表明,pH和季节是影响湿地土壤养分的潜在驱动因子.其中pH对湿地土壤养分的影响最大,为37.90％.该研究结果可为包头黄河湿地的植被重建、生态修复和科学管理提供参考依据.
