UNESCO designated sites(UDSs),including World Heritage Sites(WHSs),Biosphere Reserves(BRs)and Global Geoparks(GGPs),are a collection of focal spots deemed to be holding significant value for sustainable development within diverse environmental,social,and economic contexts.1 However,there is a clear lack of understanding and acknowledgement of UDSs’value and their specific contributions in policy-making related to *** is especially true of the 17 Sustainable Development Goals(SDGs)that are part of the UN’s 2030 Agenda.

Relative dielectric constant is an important physical factor in the theory of microwave remote sensing and electromagnetic transmission. This note reports the results of detecting relative dielectric constant from 197 rock samples. The regular pattern of the relative dielectric constant varying with microwave spectrum is revealed. The relative dielectric constants, correlated with the type, density, structure and chemical component of the rock, are discussed. The re-
