The historical environment , discussed by Karl Marx , played an outstanding role in the 20 th century when the unbalanced world history was developing jointly. The historical environment, together with the productive forces and production relations,which determines the development of society , has now become a new theoretical principle to explain socialism and its development in the 20th century . Based on Marxist theory that social development is determined by the interaction of productive forces and production relations, with regard to the variety of historical environment, different historical environment accounts for different formations of productive forces and production relations . That's why socialism could become true in the backward and undeveloped East, especially in Russia and China where the socialist road has been a sensible and justified historic choice . 在 2 0世纪东西交汇、整体而不平衡的世界历史发展中 ,突显出了马克思论述的“历史环境”的重大作用。历史环境作为社会发展的新的决定性要素与生产力、生产关系三位一体 ,成为考察 2 0世纪社会主义产生和发展的理论原则。按照马克思主义基本原理 ,决定社会发展的根本动因在于生产力与生产关系的矛盾运动 ,在考虑到历史环境这个变数后 ,不同的历史环境、生产力与生产关系的构成方式就不同 ,或者说生产关系与生产力适应的形式也就不同。 2 0世纪社会主义在落后的东方社会得到了实现 ,尤其是俄国、中国对社会主义道路的历史选择以及这种选择的必然性和合理性 ,均可由此得到说明。 The west of Hunan Province, including Huaihua Municipality, Zhangjiajie Municipality and Xiangxi Autonomous Prefecture in the upper reaches of the Lishui and Yuanshui Rivers, has much impact on the downstream valleys of the two rivers and the Dongting Lake area.

The west of Hunan Province, including Huaihua Municipality, Zhangjiajie Municipality and Xiangxi Autonomous Prefecture in the upper reaches of the Lishui and Yuanshui Rivers, has much impact on the downstream valleys of the two rivers and the Dongting Lake area. Ecological environment is vulnerable in this area. Taking remote sensing image as the major data sources, a synthetic assessment of ecological environment in the west of Hunan Province is carried out by the use of geographical information system technology. Aimed at the main ecological environment problems, form different types of factors, i.e., water and heat factors, topography and geomorphology factors, land use/ land coverage and soil erosion factor are chosen to study. Seven sub-factors, i.e., cumulative temperature above 10℃, annual precipitation, altitude, slope, soil erosion intensity, land use type and vegetation coverage are selected to transform quantitative and standardized series, thus, a complex assessment model of eco\|environment quality can be constructed with grid data, the scale of which is 100×100 m2. The synthetic assessment index of ecological environment quality is computed for every basis evaluation unit by using the model. Afterward, all of the synthetic assessment indexes of ecological environmental quality are divided into 9 grades. Meanwhile, the average synthetic assessment index of ecologic environment quality is computed for every county.The assessment shows that the synthetic assessment index of ecological environment quality in the west of Hunan Province is almost symmetry, in which the second grade, third grade and fourth grade of eco\|environment account for 85 percent of the whole. Generally speaking, the eco\|environment quality in the southeast part is better than that in the northwest part, and in valleys is better than that in hilly areas. The average synthetic assessment index of ecological environment quality is the best in Luxi County and Huaihua Municipality, and is the worst in Sangzhi County and Longshan County . 以湖南西部地区为研究区域 ,采用遥感影像作为主要数据源 ,针对区域主要生态问题 ,利用栅格数据结构为主的数字环境模型 ,建立了生态环境质量综合评价模型 .对区域生态环境质量的空间分异格局进行了研究 ,通过将评价结果与数字高程模型迭加分析 ,研究了生态环境质量的垂直地带性分布规律 ,探索适合以山高坡陡为主要地貌特征的山区生态评价方法 ,结果显示 ,湖南西部地区生态环境综合指数呈正态分布 ,大部分地区环境质量属一般 .总体环境状况东南部好于西北部 ,河谷盆地优于山地 .研究表明 ,利用遥感和地理信息系统技术进行区域生态环境评价 ,具有数据采集快速、客观 ,评价和制图自动化 ,评价结果空间定位精度高 ,直观性与实用性强等优点 The kin of Chen,whose native place is Chenzhou,Henan province,migrated to Anhui, Shandong,Jiangsu,Zhejiang,Fujian,Taiwan and some other provinces.Not only might the changes of nature and environments account for the cause of migration,but the deterioration of the political situation of that period.At the period of the end of Qing Dynasty and the beginning of Republic of China.Chen Yingshi and Chen Guofu who still did something that benefit for the nation and the people although opposed to CPC after being... The kin of Chen,whose native place is Chenzhou,Henan province,migrated to Anhui, Shandong,Jiangsu,Zhejiang,Fujian,Taiwan and some other provinces.Not only might the changes of nature and environments account for the cause of migration,but the deterioration of the political situation of that period.At the period of the end of Qing Dynasty and the beginning of Republic of China.Chen Yingshi and Chen Guofu who still did something that benefit for the nation and the people although opposed to CPC after being well-known.Both of them and after Chens taking part in the actions of anti-Qing Dynasty and crusading against Yuan Shikai.The kin of Chen played a great role for the trend of China's political and has special relations with Jiang kai-skek and the other well-known in history.Most of whom engaged in industry and commerce,concerned the reunification of the motherland,and visited relations and friends in the motherland very often.All of them can demonstrate the kin's profound love knot. 陈氏原籍河南陈州 ,后辗转迁徙安徽、山东、江浙和闽、台等地。陈氏迁徙的原因既有自然条件和环境的变化 ,也有因战争、时局的改变。湖州望族陈氏对近代中国社会经济、政治、文化有重要影响。清末民初 ,陈英士和陈果夫等陈氏族人积极参加反清讨袁活动 ,为民主革命立下巨功 ;陈果夫、陈立夫成为民国显要后曾反对共产党 ,但也做过利国利民的事情 ;陈氏家族与蒋介石等历史名人之间的特殊关系 ,对辛亥后中国的政治走向有着重要的作用 ;旅居海外的陈氏族人 ,多从事工商业 ,他们心向祖国 ,关心两岸统一大业 ,不断来大陆探亲访友 ,反映了深厚浓重的宗亲情结。
