北京妙峰山优质玫瑰生长的农业地质背景

Study on the agricultural geological background of high-quality rose growth in Miaofeng Mountain in Beijing

为研究妙峰山优质玫瑰生长的地质背景,通过实地考察、取样测试的方法,从成土地质、地质构造、地貌条件和地球化学元素含量4个方面进行分析,并基于Arcgis软件,获取门头沟区玫瑰种植区划图。结果表明:1)妙峰山优质玫瑰生长的土壤源自安山质火山岩形成的母质;2)妙峰山隆起为向斜山构造地貌,并形成山体局部小气候,构造运动形成的大量断裂加速了岩石风化,这些都对妙峰山土壤的形成和发育及土壤性质产生了重要的影响;3)妙峰山基岩中丰富的Ca、Mg、Fe、B、Zn和Mn元素极大地影响了玫瑰的优良品质;4)从妙峰山农业地质背景角度出发,划分门头沟区玫瑰种植区,在门头沟区与妙峰山相似的安山质火山岩及一定高度海拔的谷地有望成为玫瑰的种植区。在相似的气候条件下,妙峰山优质玫瑰品质主要受农业地质背景的影响。

In order to study the geological background of the growth of high-quality roses in Miaofeng Mountain in Beijing,field investigation and sampling test methods were used in this study to analysis its geological background from four aspects,e.g.soil geological background,geological tectonic background,landforms conditions and geochemical background.The zoning map of rose planting in Mentougou District was then obtained with the ArcGIS software.The results show that：1）Rose growing soil of Miaofeng Mountain derived from Andesitic Volcanic Rocks in Jurassic strata.2）The tectonic movement resulted in the uplift of Miaofeng Mountain into a syncline mountain tectonic landform.At the same time,mountain microclimate formed in this mountain area.A large number of faults formed by tectonic movements accelerated the weathering of rocks,which had important influence on the formation and development of Miaofeng Mountain soil and its property.3）The pedestal rock of Miaofeng Mountain was rich in Ca,Mg,Fe,B,Zn,and Mn,which had greatly affected the fine quality of roses.4）From the perspective of agricultural geological background in Miaofeng Mountain,the rose planting area was divided in Mentougou District.The valley region,which is similar to Miaofeng Mountain,is expected to become the planting area of roses.Its soils were derived from Andesitic Volcaniclastic Rocks with a certain elevation.The conclusion is that under similar climate conditions,the quality of high-quality rose in Miaofeng Mountain is mainly affected by the agricultural geological background.
