Understanding regional environmental heterogeneity(EH)and biodiversity relationships(heterogeneity-diversity relationships:HDRs)is the first step toward coupling environmental variables with biodiversity surrogates into regional systematic conservation ***,there is no universal method for determining regional HDRs that considers various environmental variables and biodiversity in different *** study selected 32 nature reserves as natural areas in yunnan,china,to examine regional HDRs in *** calculated 17 EH parameters(of soil,topography,and climate)and three(ecosystem,plant,and animal)biodiversity indices in the nature *** examining the explanatory power of each EH parameter and area of the nature reserve,we identified the primary parameters and constructed an optimal model for each biodiversity *** explanatory powers of these parameters varied for each biodiversity index,and those of climatic parameters were generally higher than soil and topographic heterogeneity *** of the temperature annual range,followed by area and heterogeneity of soil type,were important parameters for ecosystem diversity of yunnan and the optimal model explained 56.9%.Plant diversity was explained 54.5%by its optimal model,consisting of heterogeneity of precipitation of the coldest quarter and annual *** of temperature annual range was important for animal diversity in yunnan and explained 29.6%of its optimal *** study suggests that EH parameters can be an effective surrogate for biodiversity,therefore,we suggested that the significance and role of climatically heterogeneous regions for the conservation of biodiversity in yunnan should be further studied in the future.

Jade ware Jue is one of the most fashionable ornament in ancient china from the Neolithic Age to the Han *** this study,the remnants of jade ware Jue,from Lijiashan ancient tomb group have been tested and analyzed *** samples through a light etch surface showing glass luster and those with a severe etch surface showing earthen *** the aid of X-ray fluorescence Spectrometer(X-ray Fluorescence)test and X-ray diffraction(XRD)detection,the results show that tremolite is not the main mineral of the *** main components of the tested samples with light erosion are antigorite and talc,although the main components of the samples with severe erosion are calcite containing calcium carbonate ***,the research on jade ware Jue in yunnan culture has not only contributed to our further understanding of the jade objects from yunnan culture and the variety of jade material located in the yunnan *** also provides a basis for the trace of the history and culture through the distribution and evolution of burial hierarchy *** the same time,the microscopic observation of the tested samples manifested a residual trace of“string”at the perforation,which has played a critical role in restoring the wearing of jade ware Jue from the tombs of the ancient yunnan State and the handicraft skills at that time.
