Revisiting Sustainable Development of Dry Valleys in Hengduan Mountains Region

Dry valleys are a striking geographic landscape in Hengduan Mountains Region and are characterized by low rainfall, desert type of vegetation and fragile environment. Past efforts and resources have been concentrated mainly on rehabilitation of degraded ecosystem and fragile environment, particularly reforestation, while socio-economic development has been largely overlooked. Despite successes in pocket areas, the overall trend of unsustainability and environmental deterioration are continuing. It is important to understand that uplift of the Tibetan Plateau is the root cause of development of dry valleys, and development and formation of dry valleys is a natural process. Human intervention has played a secondary role in development of dry valleys and degradation of dry valleys though human intervention in many cases has speeded up environmental degradation of the dry valleys. It is important to understand that dry valleys are climatic enclaves and an integrated approach that combines rehabilitation of degraded ecosystems and socio-economic development should be adopted if the overall goal of sustainable development of dry valleys is to be achieved. Promotion of niche-based cash crops, rural energy including hydropower, solar energy, biogas and fuelwood plantation is recommended as the priority activities.     

土地管理制度创新与农民增收

王岗，十年建房“不下岗”

在河南省方城县赵河镇西北部的王岗村，是赵河镇面积最大，人口最多，人均耕地最少的村。全村祖祖辈辈就依赖两条水渠及渠外仅有的耕地，栽烟种粮，维持生计。     

青藏块体东北缘断层形变与中强地震

对祁连山－海原断裂带近期断层形变特征进行了初步研究，发现多场地，大范围的断层活动异常是中等强度地震发生的显著背景，并且往往与大陆地震活动的阶段性总体状况相呼应；区域形变存在明显的特征量，包括特征形态和特征时间，同一场地在不同地震前的异常特征具有重复性，但会受到背景差异显著的不同地震的影响，目前形变状况表明研究区仍具有发生中强地震的地壳运动背景。     

走旧村改造之路 建美丽富饶姚村——林州市姚村镇拆旧建新消灭“空心村”纪实

在豫西北晋、冀、豫三省交界，有一个闻名退尔的古老集镇，她西依林虑山，东绕太行余脉，地势平坦，交通便利，人杰地灵，她就是林州市姚村镇。这个古镇现有近8万人口，农民2.5万户，总面积100平方公里，耕地面积6万亩，新河公路穿境而过，举世闻名的红旗渠一、二干渠像两条绿色巨龙盘绕在姚村盆地的东、西山腰，98个自然村像一颗颗璀璨的明珠镶嵌在两龙盘绕的青山绿水盆地之中。     

中部地区主要城市工业用地的地价杠杆作用

1经济发展和工业用地价格状况 我国经济政策上的中部地区就主要包括山西、河南、湖北、湖南、江西、安徽等6省。中部6省土地面积为102．7万km^2，人口3．63亿，分别占全国的10．7％和28．1％。近年来，在国家政策的大力支持和自身努力下，中部地区城市经济都取得了长足的发展，经济发展同时也带动了土地价格的上涨，但工业用地的价格并没有相应上涨。

玛多黄河源区生态环境治理:任重道远

黄河,发源于青藏高原巴颜喀拉山北麓。玛多县境是黄河源区的主要片区,这里因处于三江源区青藏高原腹地及其特殊的地理位置和高寒多风干旱的气候,生态环境十分脆弱。近20年来,由于大气环境的逐渐变暖和人类活动的加剧如草原开发和过牧等因素,玛多县境内黄河河段、湖泊、湿地及草
