Within the context of growing economic integration in the Association of Southeast Asian Nations (ASEAN), recent questions have been raised with regard to how member states employ law as a means of regional integration to promote sustainable development. Taking into account the primacy of ecosystem services for sustainability, this study examines the coherence of legal frameworks for ecosystem services among ASEAN member states toward a unified regional legal agenda for sustainable mineral development. Analyzed along three aspects of the Ecosystem Services Approach, the paper reviews the different mining related legislations and implementing regulations of member states, and examines whether there is convergence in their legal provisions for ecosystem services. The study shows that all member states provide legal mechanisms for ecosystem management in their mining operations. However, the following could be noted: 1) a lack of coherent identification and targeting of ecosystem services despite ‘intermediate’ services being embedded in provisions for ecosystem conservation; 2) a lack of legal provisions for integration of ecosystem services in mining impact assessments, and for ecosystem services valuation, which render environmental impact assessments, compensation structures and royalty regimes inadequate; and 3) a density of legal differentials around how states allocate regulatory authorities for ecosystem management in mining. These represent a prevailing fragmentation among member states’ legal frameworks for ecosystem services, which does not create an enabling condition for legal integration in ASEAN’s regional mineral strategies for sustainable development.

在东南亚国家联盟（ASEAN）经济一体化不断发展的背景下，最近出现了有关成员国如何利用法律作为区域一体化手段促进可持续发展的问题。考虑到生态系统服务对可持续性的重要性，本研究考察了东盟成员国之间针对可持续矿产开发的统一区域法律议程之间生态系统服务法律框架的一致性。本文从生态系统服务方法的三个方面进行了分析，回顾了与采矿有关的不同立法和成员国的实施条例，并研究了其有关生态系统服务的法律规定是否趋于一致。研究表明，所有成员国都在其采矿活动中提供了生态系统管理的法律机制。但是，应注意以下几点：1）尽管“中间”服务已嵌入生态系统保护规定中，但缺乏对生态系统服务的统一识别和确定目标；2）缺乏将生态系统服务纳入采矿影响评估以及对生态系统服务进行估值的法律规定，这导致环境影响评估，补偿结构和特许权使用费制度不足；3）围绕国家如何分配监管机构进行采矿中的生态系统管理的法律差异的密度。这些代表了各成员国生态系统服务法律框架中普遍存在的支离破碎，
