The kinetics of degradation of healthy paddyfield ecosystem due to unreasonable fertilization are as follows.(1) The rice growth was interfered and the structure of microbe population was altered through applying excessive nitrogen fertilizer, while the yield of rice was decreased later and the secretion was reduced from rice root, which induced the Eh and the quantities of Bacterium and Actinomycetes declining, and the contents of MBC, MBN, MBP low in the soil. All of that made the capacity of accommodating nutrient weak in microbe ecosystem.

不合理施肥引起的稻田生态系统退化的动力学特征是：(1)重施氮肥首先使水稻植株生长受阻，同时改变土壤微生物种群结构，从而直接使水稻产量降低，稻田土壤生产力受损，并产生一系列不良次级反应：水稻生理活动减弱减少了根系分泌量，同时也降低了土壤Eh，使稻田土壤细菌、放线菌数量降低，MBC、MBN以及MBP含量下降，微生物保肥、供肥能力降低，从而土壤微生物生态系统功能弱化。

Paleoecology The investigation of prehistoric ecology as revealed by studying fossils and ancient human artifacts, pollen samples, and the mineral deposits in which such structures occur.

古生态学：指对史前生态研究的学科。主要通过研究远古形成的化石以及古人类遗迹，花粉(参见 palynology)标本以及矿质沉淀以描述当时生态环境。

To examine the influence of systemic factors on aged progenitor cells from these tissues, we established parabiotic pairings (that is, a shared circulatory system) between young and old mice, exposing old mice to factors present in young serum. Notably, heterochronic parabiosis restored the activation of Notch signalling as well as the proliferation and regenerative capacity of aged satellite cells.

为了查明系统因子对来自这些组织的衰老祖细胞的影响，我们在幼鼠和老鼠之间建立了共生态配对试验（即：一种共享的循环系统），给老鼠输入含有年轻因子的血浆，奇怪的是，异时性共生态细胞Notch信号重新激活，同时恢复了衰老干细胞增生和再生能力。

In order to provide more references for the suitability determination of eco-concrete for planting,four kinds of eco-concretes with different void statuses were fabricated,in which Paspalum notatum Flugge was planted,and the growth of the plant was observed.

为了完善植生型生态混凝土适生性的判据，拌制了4组不同孔隙状态的生态混凝土，在其上种植百喜草，考察了百喜草的表观生长情况，测定了百喜草植物体内的脯氨酸含量、根系吸收面积及根系活力。

Wang Xiaoyi discussed the impacts of persistent drought on local livelihood and whether current measures to coop with drought worked well for the long term perspective in his paper. Based on a case case study in Horqin Sandy Land, he suggested that the poverty has been more serious because of drought, it increased the production cost for rich herders, but broken the vulnerable balance in poor households; the uneven distribution of resource in household brought more social problems in the community; the wrong means to cope with drought, which focused on property and ecological compensation, would intensify the poverty problem in pastoralist.

王晓毅在文章中通过兴安盟一个嘎查的实地调查，讨论了持续的干旱对牧民生计的影响及从长期效果来看，现在应对干旱的手段是否可行的问题，文章认为持续干旱正在造成牧区的普遍贫困化，增加了大牧户的成本，但却打破了小牧户的脆弱平衡；在畜牧业收入占主导地位的情况下，资源占有的不均衡导致了更严重的社会问题；在干旱的条件下，试图通过草原产权制度的改革和补偿性的生态政策经常会在运行过程中导致生态的进一步恶化。
