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.
