清代皖西引种玉米甘薯史实及其检讨

明中叶后,美洲的玉米与甘薯越过大洋,先后来到中国安家落户,也走进皖西淮河、长江支流的一处处谷地和上游大别山区的高山腹地。玉米和甘薯是比较典型的旱粮作物,它们不太苛刻的种植条件带来了两种作物的极度扩张,从而为中国人的食物结构加进了新元素,从根本上改变了种植地民众食物不足的困境,尤其是解决了山区越冬食物不足和春荒的困难。但何炳棣"整体史学"的思维告诉我们,玉米和甘薯的引种,也带来了人口的激增;涌向山地的农民由于缺乏山地耕作的经验,又造成了水土流失和环境危急的日益严重。当然,只要能采取波伦式谨慎选择的态度,玉米和甘薯基本上是个好东西。历史的启示是,人类与自然之间只能走一条"共同进化"的路。     

鲁西陆表海高分辨层序地层及海平面变动控制

依据钻孔岩芯和测进资料，对钽西陆表海盆地含煤地层进行了高分辨率层序划分，研究了高分辨率层序地层特点及其控制因素。研究表明，鲁西表海沉积序列中不同级次旋回相互叠加，具有特征的低频（Ⅱ～Ⅲ级）和高频（Ⅳ～Ⅵ级）层序叠加样式；这种相互叠加的旋回结构受控于相互叠置的海平面变化周期，即复合海平面变化。海平面变化周期表现出非对称式突发性上升到缓慢回落的节律性，形成了不对称的旋回记录。

社会主义新农村建设微观模式探析——以四川平武、北川为例

西部贫困山区的新农村建设有着地理条件、经济社会环境、人文基础的特殊性。本文以具有代表性的平武、北川地区为例,以微观模式入手,论述新农村建设的方法,提出了“企业＋集体（合作社,协会）＋农户”的模式,同时将政府的作用引入模式之中。最后本文指出了实现这一模式的方法。     

Synopsis of the life cycles of Digenea (Platyhelminthes) from lagoons of the northern coast of the western Mediterranean

The present document reports on the large amount of data relating to digenean parasites recorded from or known to be present in various hosts in lagoons of the northern coast of the western Mediterranean, which has been compiled from the literature of more than a century. In these lagoons, at least 72 nominal species of digeneans have been recorded. This total corresponds to approximately 12% of the 584 “marine” digenean species reported for Europe. Data are provided on the life cycles of 56 digenean species. The life cycle has been totally elucidated for 44 species (25 from fish, 19 from birds), and partly for the other 12 species (seven from fish, five from birds). This means that the life cycle is known for 61.1% of the recorded fauna (44/72) and partly for 16.7%, but remains unknown for 22.2%, making it, in this respect, one of the best understood digenean marine faunas in the world. In addition, a checklist is provided dealing with the cercarial and metacercarial forms recorded from lagoons of the northern coast of the western Mediterranean, which have been described only on the basis of characters of these larval stages and which remain without demonstrated links to a corresponding sexual adult stage in a vertebrate.
