Nature and the environment are a gift from God that exists around every living thing and on which survival depends. Given the vast natural resources that Iran has at its disposal, it should be noted that the destruction of natural resources and the environment affects the quality and natural cycle of the country and has detrimental consequences for human life, animals, plants and buildings. Given that nature was created for the survival of the human race and there is an inseparable link between man and nature, so its preservation and protection is very important. Given the accelerating trend of natural resource degradation and the threat of biodiversity, one of the challenges in the field of natural resource protection is to upgrade the protection unit of such areas. The purpose of this study is to identify and rank the effective factors in improving the performance of the Natural Resources Protection Unit. The present study is applied in terms of purpose and descriptive in terms of nature and method. In order to collect, questionnaires based on multi-criteria decision-making methods used in this study (test and evaluation decision-making method and network analysis method) were used by five people. One of the senior experts with at least ten years of experience in the natural resources of Bastak city has been completed. The collected data were analyzed by Excel software and superdecision. The results of identification and effective factors in upgrading the protection unit based on network analysis show that the most weight is occupied by machines and the lowest score is allocated to system updates.
