：方兴未艾的互联智能大数据时代，引爆了传统法学领域内科学研究与法治决策内外部关系的重构，使得法学学术范式的转型与法治决策流程的再造变得迫在眉睫。如何认识法治决策与决策证据尤其是循证证据之间的关系及两者的历史流变；如何实现大数据时代决策证据的规范有效转化，法循证学方法又如何扬长避短地发挥其应有的功能等问题，就成了明确法循证学内涵与外延后业界需着力思考和解决的问题。文章以决策证据的循证使用/消费为核心，为法循证学方法在汉语法学与法治实践中的运用初步总结出一个能够与传统法学方法实现功能衔接的学科新工具，描摹出一个由浅入深、色谱递进的法循证学方法领地，概括出一个基本的法循证学方法使用流程。

In the burgeoning era of interconnected intelligent big data, the reconstruction of internal and external relations between scientific research and legal decision-making have been triggered in the field of law, which makes the transformation of academic paradigm of law and the reconstruction of decision-making process under the rule of law extremely urgent. How to understand the relationship between decision-making under rule of law and its evidences, especially evidence-based evidences, and its historical evolution; How to get and transform evidences into evidence-based decision-making in the era of big data; how to make full use of the strengths and circumvent weaknesses of the evidence-based approach in order to play its due role in it, have become the main focus of this paper on the basis of defining the connotation and extension of the evidence-based law in our previous study. The paper aims to sum up a preliminary and practical evidence-based approach which can cohere functionally with traditional methodology of jurisprudence, and mimic a chromatographic domain of scope for evidence-based law, and outlines the basic process for the evidence-based law approach in the context of the rule of law with Chinese characteristics.
