人与自然环境的关系问题，是普通关注的问题，人们对于这一问题关注的目的在于可持续发展。中国是个文明古国，中华文化之所以在长达数千年的历史而不衰，可持续。近代工业文明以前是为农业文明。KING称以中国为中心的农业为可持续农业。探讨中国传统农学理论与实践中的天人关系。从中得到启示。天人关系指的是人与大自然的关系。[1]在传统的中国人心中，农业中的人与大自然的关系具体表现为人、天、地、稼的关系。故《吕氏春秋·审时》说：“夫稼，生之者，地也；养之者，天也；为之者，人也”。其中天和地是大自然的代表，相当于现在人们所说的环境，人和稼生于天地之间，天人关系也可以理解为人与自然环境的关系，不过其中加入了稼的因素，稼同时具有自然的因素和人的因素。人按照需要与可能选择和种植作物。传统农业中人与自然环境的关系如何？过去在研究农业史时，强调人定胜天，强调人对于环境的改造，过份地强调人及其技术的作用，而技术又过分地强调土壤耕作技术。原始农业中刀耕农业和耜耕农业阶段的划分；传统农业中北方旱作技术体系的形成和南方水田技术体系的形成等，都是主要以土壤耕作技术为依据来划分的。现在，环境问题日益受到重视，人们开始重新用审视的目光看待人与自然环境的问题，在这种背景之下，一些历史地理学家开始强调环境对人的作用，甚至有学者重新祭起了地理环境决定论的大旗，[2]受此影响农业史研究中，一些学者过多地把目光指向环境及其变迁对于农业的影响，指向农业对于环境的破坏，而忽视了人的主观能动性，忽视了人对于环境的保护[3]与改造，更忽视了人对于环境的适应。这些都不符合中国传统农业发展历史的实际。我们认为，中国农业的发展受到环境的制约，环境变迁也引起过中国农业的波动，但真正决定中国农业发展的是人对于环境的适应和改造。一、环境对农业的影响中国人很早就注意到了环境对于农业的影响。同时也注意到环境是由多种因素构成的，各种因素对于农业的影响并不相同，具体说来，天和地对于作物的影响是不同的。古人将它归纳为“生之者，地也；养之者，天也。”地，即土壤。由于在构成环境的诸多因素中，土壤与作物的关系最为直接，因而也最先为人所注意。古人认为作物的种类是由“地”来决定的。经常提到的例子是：“桔逾淮而北为枳，鸐鹆不逾济，貉逾汶则死。”[4]“菘菜不生北土。有人将子北种；初一年，半为芜菁，二年，菘种都绝。有将芜菁子南种，亦二年都变。”[5]前者说“此地气然也”，后者说“土地所宜”。地气和土地，指的都是土壤。土壤是导致变异的根源。[6]在土壤中首先注意到的是土壤上生长的植被。《师旷占术》曰：“五木者，五谷之先；欲知五谷，但视五木。择其木盛者，来年多种之，万不失一也。”《杂阴阳书》则将“五谷”和“五木”一一对应起来，有所谓：禾生于枣或杨，黍生于榆，大豆生于槐，小豆生于李，麻生于杨或荆，大麦生于杏，小麦生于桃，稻生于柳或杨。”孔子也说：“平原大蔽，瞻其草之高丰茂者，必有怪鸟兽居之，且草可财也，如艾而夷之，其地必宜五谷。”植被不仅是土壤状况的标志，同时还可以用作改善土壤的物质。中国人很早就认识到，杂草“可以粪田畴，可以美土疆”，并将“于草木茂盛时芟倒，就地内罨腐烂也”，称为“草粪”。还有意识地种植一些豆科植物充当绿肥。民族学调查表明，中国南方的一些少数民族在进行刀耕火种的时候，首先选择林地而不是草地去作为土地，而在林地的选择方面主要考虑的是林木的长势和种类，而不是土壤的质地。决定什么地种什么庄稼也是根据树木，而不是根据土壤。其次是土壤的性状（颜色、手感、水份、土壤中的生物活动等）。禹平洪水之后，茫茫禹迹，划为九州，九州的土壤，各不相同，《尚书·禹贡》言之凿凿。不同的土壤进而有不同的农产品，《周礼·职方氏》记载甚详。《管子·地员》说：“九州之土，为九十物。每州有常而物有次。”书中还具体指出了九州土壤性状及适宜种植的作物。被李约瑟等称为是最早的地植物学著作。由于决定适宜作物的是土壤而不是行政区划，所以元代孟祺在《论九谷风土及种莳时月》又做了这样的发挥：“苟涂泥所在，厥田中下，稻即可种，不必拘以荆、扬。土壤黄白，厥田上中，黍、稷、粱、菽即可种，不必限于雍、冀。坟、垆、黏、埴，田杂三品，麦即可种，又不必以并、青、兖、豫为定也。”再次是地势。或认为《禹贡》中的“厥田中中”、“厥田中下”等，指的就是地势。“凡草土之道，各有谷造，或高或下，各有草木。”植物的垂直分布也直接影响到了作物的分布，古人说：“三农生九谷”[7]，所谓“三农”，郑司农（众）曰：“三农，平地、山、泽也。”（郑）玄谓三农，“原、隰及平地”。“三农生九谷”，正反映了环境因素中地势对于作物的制约。水流径于地。和土关系最为密切的便是水，有时水甚至是土壤的组成部分，如《禹贡》中所说的“涂泥”，其中的“泥”，实际上就是水和土的混和物[8]。水是生命的重要组成部分，也是生物发生变异的根源，所以古人又说：“桔生淮南则为桔，生于淮北则为枳，叶徒相似，其实味不同。所以然者何?水土异也。”[9]今人有言，“一方水土养一方人”。对于某些生物来说，水更是须臾不可或缺。如水稻，《天工开物》说：“凡稻旬日失水则死期至。”水成为发展水稻生产最大的制约因素，于是中国历史上就有了“东周欲为稻，西周不下水”的故事发生。上述因素，古人统称之为“土”，“土气”或“地气”、“水土”。不同的土壤是有不同的物产，它们之间的引种是不可能的。即使强行为之，不是死亡，就是变异。于是有“桔逾淮而北则为枳”，“芜菁南种则为菘”的说法。狭义的天，指的是环境中的气候因素。气候随季节而变化，故称之为天时，用之于农业称之为农时。《孟子》说：“不违农时，谷不可胜食也。”《吕氏春秋·审时》更从“得时”和“先时”、“后时”对六种主要粮食作物的不同生产效果作了细致的对比。来论证“时”对庄稼生长的极端重要性。宋人将地势引入到农时之中，提出天时有“地势高下之不同”[10]，认为“高下之势既异，则寒燠肥瘠各不同。”[11]元代农学家更将时与地（纬度和海拔高度）结合起来。不仅指出了气候寒暑与纬度高低的关系，而且强调共性之间的特殊性，要求人们在选择农时的时候，应当考虑当地的实际情况来决定，这就叫做“因地为时”。[12]古人尽管对农时重视有加，但是他们对天时的认识是不全面的。也就是说，古人只是注意到了气候对于作物生长的影响，而没有注意到气候对于作物分布的影响，他们把各地作物不同的原因更多地认为是土壤的不同的结果，尽管元代引入了风土的概念，部分地考虑到了气候的因素，但他们总体上还是将土壤看作是根本的原因。只是到了明末，这种认识才发生了根本性变化。徐光启认为作物栽种中的地区差异性，在引种的过程中“亦有不宜者，则是寒暖相违，天气所绝，无关于地”；是以“果若尽力树艺，殆无不可宜者，就令不宜，或是天时未合，人力未至耳”。“若谓土地所宜，一定不易，此则必无之理”。[13]徐光启明确提出了气候是引起作物分布差异的原因的观点。

文章关键词提取应该根据关键程度选取，可以根据关键程度加以大致排序选择最关键的词汇，同时关键词最好不要在一段文章中反复出现，否则适当程度就会有失偏颇。关键词是论文的重要构成部分也是文章的高度凝练，有效的关键词可以精准的反映出文章的核心内容，在论文中出现必要的学术关键词会提高论文的审核率和通过率，以上就是关于论文关键词怎么写。
