Scholar Kimberly Smith writes,"If Berry's ecological agrarianism doesn't look particularly innovative to us, it is because he makes the marriage of agrarian and environmental thought seem so natural that we assume agrarianism always implied ecological sensitivity -- or that ecological sensitivity always implied support for family farming."

学者金柏利E史密斯这麼写著：「若贝瑞的生态小农经济理论并不特别起眼，那是因为他使得田地均分的观念与环保的结合，看起来是如此的自然，我们便认定小农经济一直都包含著环保观念－要不然就是环保观念意指的是对家庭农业的支持。

To meet the needs for scientific, technological and socio-economic development in China, we proposed four areas on which the Chinese scientists should focus their study of global change and terrestrial ecosystems in future, including:(1) Metabolism and coupling mechanism of key life elements in terrestrial ecosystems in China;(2) Implications of terrestrial ecosystems in areas sensitive to global change and in important transects on global change;(3) Interactions between biogeochemical cycle of C, N, P, S in China and global change; and (4) Development of regional dynamic vegetation model which meets the actual needs of China.

中国学者在全球变化与陆地生态系统研究领域也开展了许多工作并取得了重要成绩。按照我国科学技术和社会经济发展的需求，提出了未来我国在该领域的研究重点，包括①中国陆地生态系统重要生命元素的代谢及其耦合机制研究；②全球变化敏感区域或重要样带上陆地生态系统对全球变化的影响研究；③我国的C、N、P、S生物地球化学循环与全球变化的关系研究；④发展中国特色的区域植被动态模型。

In this paper, we make an analysis on the conformation and function flow of urban ecosystem.

城市生态学将城市作为一个生态系统来进行研究，是生态学的一个重要分支[1]，特别是随着我国生态城市建设热潮的兴起，越来越受到众多学者的重视。

Lots of research work has been done in the field of definition of ecotourism, the programming of ecotourism, the management of ecotourism, the environment of ecotourism etc, but less attention has been paid on ecotourism region. The research on the evaluation and assessment of ecotourism performance has not been reported up to now.

生态旅游要求实现旅游地的经济效益、社会效益、环境效益的高度统一，成为旅游可持续发展的有效途径，符合当今世界发展的趋势和潮流，这正是生态旅游的生命力之所在，也是国内外学者热衷于研究它的原因。

S. scholar James O'Connor overcomes this and his theory is based on the materialistic view of history.

尽管多数的生态马克思主义学者都带有空想性的色彩，但美国学者詹姆斯奥康纳却克服了这一点。

Linguists expound the new theory of language species nature, language holo condition, language biological system and language evolvement discipline, which make the foundational theory of biolinguistics wider and more profound.

语言学者论证了语言物种属性、语言全息态、语言生态系、语言进化律等新的理念，使生态语言学的基础理论得到了拓展深化；提出了&零排放&语用伦理、语言公平、RLS工程等生态语言学应用理论，显示了对语用实践特有的指导意义。

This exerts negative influences for the sustainable development of coastal protection forest system. Many researchers focus their studies on the rational structure and function of sustainable coastal protection forest of Casuarina equisetifolia, try to reveal the contributing factors to cause low-value and low-effective forest and probe into its mechanisms.

鉴于此，木麻黄防护林可持续经营问题引起了国内外许多学者的普遍关注，开展防护林生态系统结构和功能的研究，阐明木麻黄低质、低效林的成因及其发生、发展的生理生态机制，从而为木麻黄防护林的合理经营提供科学依据，是沿海防护林工程建设的迫切任务。

The study of taxology and ecology of sub-aerial blue-green algae of Neimenggu was comparatively deficient in the past. As a result, my research will supply datatostudy the particular function of sub-aerial blue-green in terrestrial ecosystem.

目前国内学者对内蒙古亚气生蓝藻的分类及生态研究较少，因此这一课题有其特殊的理论价值和应用前景，为进一步探讨亚气生藻类在陆地生态系统中的详细功能提供了本底资料。

The contents of the curriculum must be acceptable by the teachers on the impelling of educational activities thus teachers hold an approval view towards the concept of using Ecological engineering method on straightening Old Zhuoshui (avg. rate 4.1). The teachers also assume that this subjects is acceptable in merging with the teaching of elementary schools environmental of education (avg. rate 3.92). Thus, this idea coheres with the everlasting preservation of the environment (avg. rate 4.08), and that teachers are willing to impel and participate in the exercise of using this issue on education within a year (avg. rate 3.51). It proves that this idea of Ecological engineering method is suitable for use of teaching environmental education issues.

教学活动推动时，其课程的内涵是需受教学者的肯定，而教师对於旧浊水溪以生态工法整治是持认同的态度(平均数4.1)，也认为此议题适合融入小学环境教育的教学(平均数3.92)，并可符合维护生态与环境永续发展的理念(平均数4.08)，且在未来的一年内教师愿意推动及参与此议题运用於教学上(平均数3.51)；显示生态工法的工程思维是适合做为环境教育议题的教学。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
