冀西北坝上地区不同植被类型的生态需水量

为了了解冀西北坝上地区不同植被的生态需水量,为该地区的植被建设提供科学依据,采用实际观测数据及Irmak-Allen公式对张北坝上地区乔木林、灌丛和草地的生态需水量、生态缺水量进行了研究。研究结果表明,冀西北坝上地区3种植被生长季的实际蒸散量由高到低为乔木林、灌丛和草地,分别为401.81 mm、358.78 mm和346.02 mm。生长季乔木林、灌丛和草地的最小生态需水量分别为243.96mm、218.35mm和211.36mm,适宜生态需水量分别为472.99mm、423.34mm和409.77 mm,适宜生态缺水量分别为198.56 mm、148.91 mm和135.34 mm。植被生态缺水量具有明显的季节性,5、6月份缺水量最大,7-10月份较低,甚至还有盈余,5、6月份进行人为补水将有助于缓解植被的干旱胁迫。冀西北坝上地区的降雨量能够满足乔木林最小生态需水量的要求,但与适宜生态需水量差距较大,不足以使乔木林维持良好的生长状态,这是导致坝上地区杨树防护林退化的主要原因。

北京山区泥石流分布特点

一 北京山区是泥石流多发地区之一。因此,对其发生的时间、空间规律进行分析研究,将为山区农业区划和泥石流防治规划提供某些依据。 北京地处季风气候半干旱地区,本区发生泥石流的必要条件之一,就是需要一定的降雨方式,或者说需要有一种特殊的降雨过程。 一般情况下,暴雨接踵于连阴雨之尾,常会发生泥石流。譬如,1950年8月4日房山县大石河地区发生的泥石流,据幸存的杨家两兄弟介绍:连阴雨至第三日早饭前,骤然暴雨倾盆,只见从大西沟而下的泥石流,裹携着几十株核桃树,直立、倒卧或揉折其中,凶涌而下,至谷地拐点涌上山坡,扫过半坡上的杨家宅院。结果使其全家九口仅幸存他兄弟二人。同日,清水河在“室外白茫茫一片,数步之外不辨人物”的暴雨中,

北京山区沟域经济发展的空间结构

Valley economy is a new mode in mountainous area development that is defined by various characters of valley development,and is a distinguishing economical geographic pattern for mountainous area development.The special spatial coupling relations in the dis-tribution of different mountainous elements in valleys are new subjects for the mountain de-velopment studies,and such studies are meaningful both for researches and practices.Based on the long term researches on mountainous area development and following a brief exploration into the connotations and the spatial organizing process of valley economy,the authors analyzed the present situations of the development of valley economy in Beijing’s mountainous areas,studied the characteristics and the impacts of the spatial structural changes of the valley economy in Beijing’s mountainous areas,and finally proposed a rational arrangement of the spatial structure of the valley economy in Beijing’s mountainous areas.It is considered in this study that valley economy plays an important role in the development and functional transformation in Beijing’s mountainous areas in the new epoch.Firstly,valley economy is not outlined by the administrative boundaries,and it connects most of the villages in the mountainous areas roughly along the major transportation lines.Therefore,valley economy can exert positive influence on the development in the mountainous areas,at least in the aspects such as the rearrangement of industrial structure in the mountainous areas and the coordinated development of rural and urban areas.In addition,it is found that the valley economy in Beijing’s mountainous areas is evolved in a spatial organizing stage of secondary concentration,which is characterized by resource-saving,ecological protection and industrial optimization.Therefore,the development of valley economy will be helpful to the coordination between ecological protection and economic development in the mountainous areas,and will promote the integrated development of the mountainous areas.The developing mode of the valley economy in Beijing’s mountainous areas will provide the basis for the decision-making in the transformation of the functional roles of Beijing’s mountainous areas,and on the other hand,will present experiences for the studies in the mountainous areas outside of Beijing.
