No other habitat is as agriculturally useful to humans as grasslands.

再没有比草原更适合于农业的土壤资源了。

In addition, reasonably use reclaimed water resource and develop scientific agricultural measures can effectively pervert soil salification and basification.

此外，合理利用再生水灌溉以及制定科学的农业措施能够有效防止土壤盐碱化。

Not suitable for development of agricultural soil: chernozem farming, farming chestnut soil, covering an area of 22.36 hectares.

不宜发展农业的土壤有：耕种黑钙土、耕种栗钙土，面积22.36万亩。

For such reasons, the author investigated comprehensively on cropping systems and agriculture development in Fenxin County from 2002 to 2004, using mathematics model and GIS, discussed the cropping systems characteristic and development orientation and optimized the cropping systems spatial distribution. The data were collected from literature, questionnaires to experts and farm households, on-site investigation and field experiments. The main results are as follows:1,Because of inconsequent exploitation and management of the resources, rapid increasing population in hilly region of red soil, the stress on soil, deterioration of farmland ecological environment and soil gleization become more and more serious. Natural features , water and thermal resources and species are abundance.

基于以上目的，作者于2002-2004年，通过资料调研、专家咨询、农户调查、实地考察和田间试验等手段，对江西奉新县的种植制度和农业发展进行了全面的调查，通过建立数学模型和运用地理信息系统，对奉新县的种植制度的特征和发展方向进行了全面的论述，并且对种植制度进行了空间布局优化，主要结果如下： 1、红壤丘陵区由于长期以来对资源的不合理利用和掠夺式经营以及人口的急剧增长，土地压力上升，农田生态环境恶化，土壤潜育化，土壤肥力退化非常严重，但区内自然条件优越、水热资源总量丰富、物种丰富，具有一定的区位优势，为区内种植制度调整提供了有利条件。

For instance, we repeatedly warn the farmers not to irrigate, yet they secretly go to the vineyard and irrigate at night because they think the soil is too dry.

例如，即便我们再三警告他们不要灌溉葡萄园，这些农户仍然会在夜间偷偷灌溉。从传统农业的"经验"来看，葡萄园的土壤太干了；同时，我们的庄园又在不断的向农户强调，干燥的土壤有利于葡萄的生长。

In China, crop strews and energy crops are the main resource of bioenergy under the condition of secure food safe. There are lots of resource of crop strew, and only the main tree food crop can produce about 0.5 billion ton strew, which can maintain soil carbon and was used as the resource of bioenergy. In addition, there are about 0.1 billion hm2 waste hills and and that is suitable for farming or forestry can be used for the development of agriculture and forestry energy.

在保证粮食安全的前提下，农作物秸秆和能源作物则是生物质能的重要原料，我国农作物秸秆资源丰富，仅三大粮食作物每年就可以产生5×10~8t左右的秸秆，除了部分还田以保持土壤碳含量外，尚有可用于生物能源的部分，此外我国尚有近1×10~8 hm~2宜农、宜林荒山荒地，可用于发展能源农业和能源林业，而且我国能源农林业物种资源非常丰富，农业主要有木薯、甘蔗、甜高粱、油菜、花生、向日葵等，林业有漆树科的黄连木，无患子科的文冠果，大戟科的小桐子，山茱萸科的光皮树等，以此为原料可以进一步加强我国的生物液体燃料等的生物质能利用方式。

The reason included five aspects:①the effect of physical environment: the open geographical environment and barren soil urge the Greeks to look for development outward while the close geographical environment and advantaged condition for agriculture shaped the Chinese conservative thought and obstructed their steps of going out.②the advancing and blocking of the economic: the frequent trade offered an abundant living supply and open view while the self-sufficient agriculture with restraining trade rigidified the thought.③ the difference in politic institute and situation: the democracy polis of ancient Greece is exclusive in the ancient world. It shaped the atmosphere of freedom, democracy and adversary. While the monarchy in ancient China pursued the "united country" and shaped the atmosphere serving for politic and consolidating thoughts.④the guiding of traditional culture: the Greeks pursued freedom and wisdom and were curious about nature while the Chinese adored ancestor and obeyed the authority and prefer to pragmatism.

出现这种关系的原因本文从以下五点进行分析：①自然环境的影响：古希腊开放的地理环境和贫瘠的土壤种植条件促使古希腊人向外寻求发展，而古代中国封闭的地理环境和优越的农业环境阻碍了中华民族外出的脚步和开放的思维；②经济条件的推动与束缚：工商业发展的农业经济和自给自足的小农经济所创造的物质条件和对思维影响的差别是很大的；③政治制度和政治形势的差异：古希腊民主城邦制在古代世界是独树一帜的，它所营造的自由、民主的氛围和古代中国追求&大一统&的君主专制下为政治服务、思想趋向统一的氛围截然不同；④传统文化的引导：古希腊人在长期的城邦生活和参与海外贸易的生活中形成的开放、自由、对自然充满好奇、追求智慧等民族文化传统与中国保守崇古、讲究实用的文化传统形成了鲜明的对比；⑤思想家本身(来源：A58BC论文网www.abclunwen.com)目的不同：古希腊思想家为了变得智慧而获取知识，享受知识带来的乐趣，而古代中国思想家的一切动机都是为了&成化天下&、&以政裕民&服务。
