基于遥感影像的决策树分类,结合土地利用图,将北京市农业地表覆盖划分为春玉米、冬小麦、果园、林木苗圃、牧草地、设施农业和畜禽饲养地。考虑海拔、坡度和土壤质地三个因子将北京市分成10个景观区,在景观分区和不同农业用地基础上划分出39类农业景观单元。利用基于遥感影像计算的归一化差异植被指数,结合实地调查验证,分类出北京市冬春季裸露农田。结合景观分类,分析了不同景观单元冬春季地表裸露情况。结果表明:2007—2008年冬春季裸露农田共8.05×104 hm2,主要分布在延庆盆地、密云水库北岸和城区边缘的近郊农业区;海拔和土地利用方式对裸露情况影响较大,其中山区春玉米和平原果园裸露情况绝对面积较大,分别占到总裸露农田面积的40%和17%,牧草地、林木苗圃与设施农业地裸露程度较高。基于不同景观单元裸露程度,结合绿肥种植、保护性耕作、生草覆盖等裸露农田治理方法,探讨了北京市农业产业和景观一体化建设策略。 相似文献

The Frome near Stroud is an unusual example of a Cotswold stream that flows west, against regional topographic and geological dips. As a result, a deeply incised and irregularly indented valley has been carved through a succession of Jurassic strata of varying competencies and permeabilities. The landscape has been modified by intense, locally variable periglacial erosion during Devensian times, resulting in a number of characteristic landforms including landslip, valley bulging, and limestone cambering. This study assesses the importance of spring and river discharge upon the sculpting of such a unique landscape. An extensive discharge survey of 67 hillside springs has revealed two well defined springlines that form at stratigraphical interfaces. Groundwater issues in greater abundance from the lower, Inferior Oolite, aquifer; discharge here is more regular throughout the year. Groundwater flow is a function of the regional SE strata dip, and of the heavily fissured character of the limestone, which provides rapid preferential flow pathways. Discharge of the River Frome was measured at four localities and cannot be explained by a simple model using upstream drainage area, as the channel can run completely dry over limestone in summer. The position of the springs has influenced the development of a line of settlements along the valley sides, as well as the proliferation of industry in the valley floor, with mills sited at points of high stream power. Geology affects valley shape, width, and orientation; the structure of the jointed limestone aquifer guides spring discharge and the orientation of many dry valleys. 相似文献

为了全面系统地认识济南十大泉群,文章采用对比分析法揭示十大泉群分布、流量、景观及水质特征,通过水文地质结构精细刻画与泉水排泄条件分析,进一步明确十大泉群成因差异性,归纳泉水形成模式,揭示十大泉群水循环的差异性。结果表明:十大泉群基本特征可大致分为两类,即排泄区6个泉群均为上升泉、南部补给区4个泉群均为下降泉;十大泉群形成模式可划分为五类,即构造凸起—灰岩“天窗”成泉、构造凸起—裂隙连通成泉、浅埋多层砂层与高渗透黏土导通成泉、断裂切割成泉和侵蚀溢流成泉模式;宏观上济南十大泉群水循环受北倾单斜构造控制,其输入条件、输导系统和输出方式差异较小;微观上6个承压型泉群泉水输出方式差异性明显,其灰岩覆盖层类型、厚度、渗透性及灰岩顶板埋深差别较大,导致泉水出流形态、流量及水质不同,形成各自独特的景观。岩溶泉水微观成因的详细研究可为济南十大泉群分类保护提供重要地质依据。 相似文献

Study on urban construction planning based on karst landscape protection contributes to sustainable development of urban construction in karst area. Jinan is a city famous for karst spring water. Karst landscape plays a decisive role in urban construction. Through hydrogeological analysis, the distribution characteristics of karst mountain, cave, gully and flat dam in Jinan are analyzed. It is revealed that various karst landforms are involved in the spring circulation process to varying degrees. Some karst landforms have been destroyed in the process of urban construction and the karst landscape has been overexploited resulting in the direct or indirect weakening of spring water recharge and infiltration capacity and the decrease of spring water flow. Through the study of the principle of organic combination of karst landscape and urban construction planning, on the basis of protecting the ecological environment of the south, paying attention to the overall protection of the karst geomorphology system and the principle of accessibility of the karst landscape, the development countermeasures guided by urban planning are put forward based on karst landforms protection. On the basis of fully considering the special karst landform conditions in Jinan, the countermeasures are that the ecological control red line of urban construction planning should be set up based on karst mountains and valleys in southern of Jinan City. It is suggested that the bare carbonate rock continuous mountain foot line in the direct recharge area should be taken as the south control red line of urban development and included in the overall planning. The urban landscape is mainly displayed in the main axis based on karst mountains and springs, constructing East-West Axis-characteristic Landscape Belt along the Wufeng Mountain-Langmao Mountain-Hero Mountain-Qianfo Mountain-Long cave-Panlong cave-Jinping Mountain line and North-South Axis Landscape Belt along the Baotu Spring- Qianfo Mountain line, Baiquan-Panlong cave line, Baimai spring-Dajian Mountain line. Based on the karst river valleys and the river system, the urban spatial pattern is constructed, forming ecological corridor, restoring infiltration function of river. The form of urban construction should be shaped based on karst landform and the river system. The main form is semi-star like radiation type and the combination of central intensive type and zonal type. Based on the whole protection of karst geomorphology system and the scientific molding of karst landscape, the ecological landscape city with the symbiosis of spring and urban can be built. 相似文献
