甘肃省重要古植物化石产地区划及保护利用

古植物化石是地质历史时期各类植物实体或遗迹的残留。对古植物化石产地进行系统的调查和区划研究是开展古生物化石保护和利用工作的基础。在资料研究和实地调查的基础上,对甘肃省24处重要古植物化石产地进行了评价和区划研究。甘肃省古植物化石产地可划分为北山地区、祁连山——河西走廊地区、鄂尔多斯和秦岭地区4个古生物化石大区以及6个古植物化石产地集中区。根据古植物化石产地的科学价值和美学价值,具体从科学性、稀有性、完整性、保存程度、可保护性5个单因素分别对24处重要古植物化石产地进行了评价。在单因素评价基础上进行了综合鉴评,共鉴评出世界级化石产地1处,国家级化石产地7处,省级化石产地16处。根据产地自然区划、行政区划等要素划分了古植物化石产地集中保护区6个。根据保护区内古植物化石产地级别及重要程度,划分出特级保护区2个,重点保护区2个和一般保护区2个。提出对重要古植物化石产地实行化石标本保护加原产地保护的建议。

Physical regionalization,protection and utilization of significant fossil plant localities in Gansu Province

Fossil plants are the remains of various plant entities or traces in geological history.Systematic investigation and regionalization of fossil plants are the basis for the protection and utilization of fossil resources.On the basis of field investigation and data analysis,we evaluated and study on regional division of 24 significant fossil plant localities in Gansu Province.These fossil plant localities can be divided into 4 regions,which is Beishan,Qlianshan-Hexi corridor,Ordos and Qinling area,and further 6 subareas of concentrated distribution area.According to the scientific and aesthetic value of the localities of fossil plants,the scientific nature,rarity,integrity,conserve degree and protectabilities of 24 localities have been estimated,and appraised 1 world level,7 national level,and 16 provincial level fossil plant localities through comprehensive analysis of the above evaluation results.According to the natural and administrative division of the fossil plant localities,6 conservation areas are divided.Basis on the appraisal level and importance of fossil plants localites,it can be divided into 2 super,2 key and 2 general reserves.It is proposed that carrying out a proposal of fossil specimens preservation combine origin localities protection to these significant fossil plant localities.
