Ancient times the Babylon civilization located the environment belonged to the subtropics desert climate, but benefitted from two rivers, young sent pulls the bottom river and the Tigris River mother's gracious gift, was having the exceptionally broad impact plain, but by was in the arid few rain in the middle of the desert climate, on the one hand thus created the local wooded area to be very few, on the other hand was the great plains which so stretched to the horizon smoothly like baffles, from this has become the sierra absolute forbidden area, from this occupied the plain center region people, even if wanted to use the firm stone material, also could because was far away, either was gives way before difficulties looks Shi Xing to sigh, either was after pays the extremely soaring price, shipped in by farSeveral stones only can use in actually carving the magnificent precious tombstone, even was in some plain person all not once has seen the mountain appearance for a lifetime, in brief took root in two river basin Cuban Billen civilization, finally is framed was the soil texture civilization, they created the cuneiform character, all could not but engrave above the thin clay tablet, was recording the exceptionally precious history, obviously in the different region humanity, all was influences subtly sparely no effort regarding the side each kind of environment resources use.

古代巴比伦文明所处的环境属于亚热带沙漠气候，但得益于两条河流，幼发拉底河与底格里斯河母亲般的恩赐，拥有着异常广阔的冲击平原，但由处于干旱少雨的沙漠气候当中，从而造成一方面当地森林面积很少，另一方面就是如此一望无垠平坦如砥的大平原，由此成了山脉的绝对禁区，由此处在平原中心区域的人们，即使想使用坚固的石头材料，也会因为路途遥远，要么是知难而退望石兴叹了，要么是在付出极为高昂的代价后，远远运来几块石头却只能用于雕刻华丽珍贵的墓碑，甚至是有些平原中的人一辈子都不曾见过大山的模样，总之植根于两河流域的古巴比伦文明，最终被定格为土质文明，就连他们所创造的楔形文字，都不得不刻印在薄泥板之上，来记载着异常珍贵的历史，可见不同区域内的人类，对于身边各种环境资源的利用都是潜移默化不遗余力的。

The geometry of canopy and interception of photosynthetically active radiation were measured.

通过实测和理论计算，结果表明：高原地区冬小麦叶片比平原地区的更趋于直立，具有比平原地区低的消光系数，能够容纳较大的绿叶面积和有效穗数；当冠层对PAR的截获率趋于饱和时，高原地区麦田可容纳的最大绿叶面积可达8.6，是平原地区的1.4倍左右；开花到成熟期间的叶日积大约可达平原地区的2倍，绿叶面积持续时间长；整个生长季期间，高原地区的PAR总量是平原地区的1.7倍，单位绿叶面积所截获的PAR是平原地区的1.3倍，又由于其叶片的趋于直立，故从上到下叶片受光比平原地区更均匀和充分，群体光合潜力高，对PAR的利用率更高。

It is well known that Huang-huai-hai Plain flourished around Han and Tang dynasties, not only boasted of the highly developed agricultural economy, handicraft industry and cultural education, but also of the population quality and proportion. while the physiognomy of the Plain has changed greatly since Song and Yuan dynasties due to the frequent deluge and the river course change of Yellow River, which caused the changes of the trace elements amount in the plain\'s soil, especially the decrease of virtual zinc which caused the cultural developing process to stagnate gradually after Song and Yuan dynasties. Trace elements like a invisible hand worked uniquely on cultural developing process.3The geographical environment and the morbid population of Lin Xiang Kingdom in Sun-Wu Kingdom Period.

二地理环境下的土壤微量元素的变化状况与历史时期黄淮海平原文明进程的关系：众所周知，汉唐时期是黄淮海平原地区文明程度最高的时期，不仅农业经济、手工业经济和文化教育高度发展，而且人口素质和人口比重也是占据极为重要地位；但是，由于黄河的频繁泛滥和改道，不仅造成了黄淮海平原地貌的巨大变化，而且也引发了黄淮海平原土壤微量元素的变化，以致有效锌严重缺乏，从而使得宋元以后的黄淮海平原的文明进程逐渐停滞下来；而在此过程中，土壤微量元素锌像一支看不见的手在起着独特的作用。
