为更好的加强环境保护，我国建立了环境公益诉讼，从目前实施现状来看也取得了较好成效，但是目前就环境行政公益诉讼而言，仅停留在事后救济型环境行政公益诉讼阶段，而“预防本位“原则一直以来都是环境保护的核心原则，实践中也出现了对于预防性环境行政公益诉讼的需求，尤其是生态破坏型环境行政公益诉讼更显示出预防措施的急迫性。因此本文在进行论证和制度建设的过程中，将以“自然之友诉云南怒江州环保局案”作为出发点，结合在前期项目调研中所阅读的共计707个行政公益诉讼案件判决书，以及2018年7月至2019年3月在浙江省高级人民法院，西安市铁路运输法院、西安市雁塔区人民检察院、成都市龙泉驿区人民法院、以及四川省江油市人民法院所记录的10余万字的访谈。以期更好的将环境行政公益诉讼理论与实践结合，完善该制度。
