Microclimate and geophysical studies are commonly applied to the characterization of karst systems although they are usually used separately. The main purpose of this manuscript is to show how the analysis of the data from both these research methods is a useful tool in the characterization of karst systems and we present the analysis of a specific case study: the Nerja- Pintada caves system. The joint analysis of the Nerja Cave and external air data (mainly temperatures) and the pre-existing gravimetric data of its surroundings (residual gravity anomaly map) have allowed us: 1) to postulate the existence of an unknown great cavity located near to the Nerja Cave and with direct influence in its ventilation and 2) to propose a new model of the Nerja-Pintada caves ventilation based on the changing connection between a "main cavity" system (Nerja Cave), with basically a transmissive function of airflows and an "annex cavities" sub-system, with different functioning as far as the airflow is concerned: transmissive in the case of Pintada Cave and capacitive in the case of the geophysically-located cave.
微气候和地球物理研究通常应用于喀斯特系统的特征描述，尽管它们通常是分开使用的。本文的主要目的是展示如何分析这两种研究方法的数据是描述喀斯特系统的有用工具，并介绍一个具体案例研究的分析：内尔哈-平塔达洞穴系统。对内尔哈洞穴及其外部空气数据（主要是温度）和周围已有重力数据（剩余重力异常图）的联合分析使我们能够：1）假设在靠近内尔哈洞穴的地方存在一个未知的大洞，对其通风有直接影响；2）根据一个“主洞”系统（内尔哈洞穴）与一个“附属洞”系统之间连接的变化，提出一个新的内尔哈-平塔达洞穴通风模型，该系统的气流传输功能基本相同，而附属洞系统的气流传输功能则不同：在平塔达洞穴的情况下为传输性，而在地球物理定位洞穴的情况下为电容性。
