By view of the history and objectives of the protected areas’investigation and evaluation,the criteria of geological survey and evaluation in the national park are defined to discover geological knowledge of the Earth’s“time,space and evolution”,that is to identify both geological events with national significance for the national park candidate sites,and the geological mechanism of its naturalness,uniqueness,superlative beauty,diversity and integrity in order to provide geological support for the conservation and management of the most important natural ecosystems and natural landscapes there The geological events meeting national criteria in the Baizushan national park of Zhejiang province are Zircon crystals of Hadean continental materials of 4.0~4.2Ga found in the Mesoproterozoic metamorphic rocks,the volcanic events of the Mesozoic arc—basin acidic magma and subtropical coastal mountain landform structure of “Peak—Ridge—Hill—Valley (basin)”from rhyolite mountain ridge to the valley bottom of granite—metamorphic rocks. The evolution and structure of the landforms are basic for the park’s most important natural ecosystems,water source area of regional river systems and superlative natural landscapes.The protection of integrity and process’s naturalnesss of the geomorphic structure there is basic for natural evolution of the important ecosystems and sustainable supply of ecologic products.
