Resources Analysis and Protection Strategies of Ancient and Famous Tree in Chenghai District

古树名木是人类珍贵的自然资源,为全面了解澄海区古树名木的资源特征,进行科学地保护,对澄海区古树名木进行了实地调查,对种类、数量、空间分布特征及生长状况等方面进行分析。结果表明:澄海区现有古树名木253株,隶属13科17属18种;其中,一级古树4株,二级古树25株,三级古树224株,以三级古树为主;古树名木在澄海区11个街道(镇)均有分布,主要分布在乡村,其中莲下镇古树名木数量最多;古树名木总体的生长势较好,生长环境较好,但仍有数株古树生长势较差以及生长环境较差,需要进一步加强保护管理,根据古树名木生长状况,制定“一树一策”保护方案,采取扩大生长空间、土壤改良、支撑加固或进行生理复壮等技术措施确保每一株古树都能得到科学、有效地保护。

Ancient trees are precious natural resources for humans,and it is necessary to comprehensively understand the resource characteristics of ancient trees in Chenghai District and carry out scientific protection.Through field investigations of species,quantity,spatial distribution characteristics,and growth conditions,it was found that there are 253 ancient trees in Chenghai District,belonging to 18 species of 17 genera in 13 families.Among them,there are 4 first-class ancient trees,25 second-class ancient trees,and 224 third-class ancient trees,mainly third-class ancient trees.Ancient trees are distributed in all 11 streets(towns)in Chenghai District,mainly in rural areas,with the largest number in Lianxia Town.The overall growth of ancient trees is good,and the growth environment is also good,but there are still several ancient trees with poor growth and poor growth environment,which need to be further strengthened in protection and management.Based on the growth status of ancient trees,a"one tree and one policy"protection plan is formulated,and technical measures such as expanding growth space,soil improvement,support reinforcement,or physiological rejuvenation are taken to ensure that each ancient tree can be scientifically and effectively protected.
