中国西南农业土地问题研究

中国农业开发滞后,农民增收难的原因,从根本上来说,应该归咎于人地矛盾突出问题。中国人口已达13亿,人均耕地只有1．43亩。在中国现今的条件下,耕地对农民来讲,依然是他们惟一赖以“生存”的基本生产资料,是他们维持活命的物质基础,是他们的命根子。     

保护和集约利用开发区建设用地实现县域经济跨越发展

近年来，由于受诸多因素的影响和制约，宾县没有突破以传统农业为主的经济发展格局，致使农业大而不全、工业弱小、第三产业不发达，与周边市县的发展差距不断加大。为了从根本上实现经济的跨越发展，从解放思想入手，在大调研、大考察、大讨论的基础上，确定了“工业强县、牧业富民、旅游带动、外力牵动”的经济发展思路。把招商引资，借外力发展壮大工业经济做为主攻目标和突破口，以工业经济的率先发展带动整个县域经济的快速发展。因此，借宾西镇的区位优势，辟建了宾西经济开发区。2002年9月，经     

潢川县土地整理注重实效

近年来，潢川县以保护耕地总量动态平衡为目标，逐年加大上地整理复垦力度，不断增加耕地面积．提高土地产出率．为农业结构调整、粮食基地建设和基础设施建设构筑保障平台．促进了当地经济的可持续发展。从去年初至今年9月份，全县累计实施土地整理复垦面积3267亩，净增耕地2665亩。     

日本帝国主义者对我国的地质调查和矿产掠夺:不动枪炮的侵略

1945年8月15日,日本正式宣布无条件投降。9月2日,在美国军舰“密苏里号”上,日本外相重光葵和参谋总长梅津美治郎代表日本政府在投降书上签字。9月3日,中国国民政府下令全国欢庆三天,     

国外地质调查成果社会化服务及发展趋势

地质调查工作,诞生于社会生产,同时也服务于社会经济的发展.但其服务范围却是个不断扩大的过程.世界上最早成立专门地质调查机构的是于1835年创立的英国地质调查所.此后,各国开始建立作为政府机构的地质调查所,调查本国的资源,为社会生产服务.起初地质调查所的基本任务是基础地质调查（进行地质填图）和区域矿产评价工作.20世纪30年代以后,地质勘查工作不仅成为矿业开发不可缺少的先行步骤,还以其独特的功能进入水文、工程、环境等诸多领域,与社会生活的结合越来越广泛.     

广西公益性地质调查的主力军--记广西区域地质调查研究院

众所周知,矿产资源是国民经济赖以生存和发展的“粮食”、“血液”,故广大地质工作者被称为国民经济建设的“先行者”。而对于从事地质工作基础中的基础——区域地质调查的工作者来说,则是先行中的先行。因为,区域地质调查成果不仅是地质找矿的基础资料,同时也是国民经济建设各部门必不可少的基础地质资料,具有无可估量的经济价值、社会价值和科研价值。

2003年中国，人均GDP超过1000美元，这是人类社会发展进程中一件大事。对中国来说，我们成功地完成了第一步战略构想，从基本小康向全面小康社会迈进；从全球框架看这一事实，13亿人口的“脱贫”对促进世界经济发展将起到发动机的作用。世界各国政要和经济学界人士赞不绝口，     

Effect of Ploughing Depth on the Growth and Yield of Heracleum candicans： a Threatened Medicinal Herb and a Less-explored Potential Crop of the Himalayan Region

This paper examines the effect of ploughing depths （A -- 60 cm, B -- 45 cm and C -- 30 cm） on the growth and yield of Heracleum candicans Wall （Apiaceae）, a threatened medicinal herb of the Himalayan region. This less-explored plant is being suggested as a potential crop for the mountain agriculture. The study was carried out in an orchard in Himachal Pradesh, India at 2500 m altitude, for two successive growth years. During the first year, all plants remained in juvenile state; in the second year, nearly 65 % plants produced flowers only under 60cm ploughing depth. Among its morphological traits, plant height, collar diameter and aboveground flesh weight were found to be strongly correlated （P 〈 0.01） with the belowground biomass during the first year （r =0.968, 0.925 and 0.973, respectively） and during the second year （r=0.945, 0.928 and 0.775, respectively）. Increase in the ploughing depth was significantly correlated （P〈0.01） with all growth parameters, including the belowground dry weight, marketable portion of the produce. The belowground biomass （commercial yield; 16.28 Qt/hec） at depth A was about 2.6 and 4.7 times higher than those recorded at depths B and C, respectively. The results clearly justify the importance of deep ploughing and this paper strongly recommends it for economically sustainable cropping.     

Resource Flows of Villages with Contrasting Lifestyles in Nanda Devi Biosphere Reserve, Central Himalaya, India

Resource use efficiency analyses of village ecosystem are necessary for effective and efficient planning of resource utilization. This paper deals with economic and energy input-output analyses of different components of village ecosystem in representative buffer zone villages, which are practicing transhumance and settled way of lifestyles in Nanda Devi Biosphere Reserve （NDBR） of Garhwal Himalaya. While the villages practicing transhumance used various natural resources spatially segregated,the villages practicing settled way of lifestyle have to manage resources from a limited spatial area through rotation and varied extraction intensities. Forests subsidized the production activity in both type of villages and the per capita resource extractions were found to be greater in tran~humance village than settled village. Though crops provided maximum energy, in terms of economic criteria, animal husbandry played important role in both settled and transhumance villages. As villages representing both the situations showed different ways of adjustments to the conservation oriented land use changes, management authority needs to address the eco-development plans fulfilling the aspirations of all people traditionally using the resources of the Reserve to reduce the conflicts and encourage their participation in the conservation of the area.
