    • 摘要:研究目的】地质建造是地质环境的载体,研究地质建造与生态特征的相关性,有助于正确认识生态问题的成因,服务生态环境精准修复。【研究方法】本文选择兼具低山、丘陵、平原的罗山县为研究区域,在罗山县地质背景和构造演化特征梳理的基础上,划分出13个地质建造类型;基于剖面调查、数据统计、水文参数试验等手段,从岩石、土壤、水文地质、地形坡度四个方面对4个典型地质建造的地质特征进行分析,并对生态特征和地质建造的相关性进行了探讨。以水土流失为例,基于地质建造进行了空间分布、成因分析和修复建议。【研究结果】结果表明,从低山丘陵区白垩纪酸性岩浆岩建造到丘陵岗地区白垩纪陆相火山碎屑岩-熔岩建造,其母质层及土壤层厚度总体不断增加,其砾石含量及砂的含量逐渐变少,土壤颗粒粒度变小,因此土壤质地由砾石土(砂质壤土)、砂质壤土、粉质壤土、壤土逐渐变化;植被由天然次生林向人工种植的经济林过渡,植被类型由多样性趋于单一性,但树高胸径不断增大;地质建造与生态特征相关性较强。基于地质建造的成因分析表明,水土流失在不同地质建造发育程度不同,其中白垩纪酸性岩浆岩建造内发育最严重。水土流失问题与不同地质建造内的地形坡度、岩石的矿物组成和粒度有较强的相关性。【结论】以建造为单元分析生态特征具有较好的针对性和应用前景,能够更多体现地质对生态的约束,研究结果可为罗山县生态保护和水土流失等生态问题精准修复提供地学依据。

       

      Abstract: This paper is the result of ecological geological survey. ObjectiveFormation is the carrier of the geological environment. Studying the correlation between formation and ecological characteristics is helpful to correctly understand the causes of ecological problems and serve the precise restoration of the ecological environment.Method In this paper, Luoshan County, which has both low mountains, hills and plains, is selected as the research area. On the basis of combing the geological background and tectonic evolution characteristics of Luoshan County, 13 geological formation types are divided; Based on profile survey, data statistics, hydrological parameter test and other means, the geological characteristics of four typical geological formations were analyzed from the four aspects of rock, soil, hydrogeology and terrain slope, and the correlation between ecological characteristics and geological formations was discussed. Taking soil erosion as an example, the spatial distribution, cause analysis and restoration suggestions are carried out based on geological formation. Results The results show that, from the Cretaceous acid magmatic rock formation in the low mountain and hilly area to the Cretaceous continental pyroclastic rock-volcanic formation in the hilly area, the thickness of the parent material layer and soil layer has been increasing, and the content of gravel and sand has increased. Gradually less, the particle size of the soil becomes smaller, so the soil texture gradually changes from gravel soil (sandy loam), sandy loam, silty loam, and loam; the vegetation transitions from natural secondary forest to artificially planted economic forest, and the vegetation type changes from diversity It tends to be single, but the tree height and diameter at breast height are increasing; the correlation between geological formation and ecological characteristics is strong. The genetic analysis based on geological formations shows that soil erosion develops differently in different formations, among which the Cretaceous acidic magmatic rock formation is the most serious. The problem of soil erosion has a strong correlation with the terrain slope, mineral composition and grain size of rocks in different formations. Conclusions Using formation as a unit to analyze ecological characteristics has better pertinence and application prospects, and can more reflect the constraints of geology on ecology. The research results can provide a geological basis for accurate restoration of ecological protection and soil erosion in Luoshan County.
