The Lower Devonian Lianhuashan Formation is unconformly unlained by Cambrian strata due to Early Paleozoic Yunan orogeny and Kwangsian orogeny in Dayaoshan area of Guangxi. The new petrology and whole-rock geochemical data of Lower Devonian Lianhuashan Formation in Dayaoshan area were presented in order to constrain their provenance and sedimentary tectonic setting. The sandstones are composed of the predominated moderately sorted and rounded quartz and sedimentary lithic fragments, indicating a close detrital provenance. These samples have obviously high SiO2 contents ( 7 4. 19 % - 95. 35 % with an average of 85. 72%), low Al2 O3 contents 0. 23%-14. 73% with an average of 6. 48%), TiO2 contents (0. 09% -1. 05% with an average of 0. 38%) and Al2 O3 /SiO2 (0. 01- 0. 20). The sandstones have low REE contents ( (12. 48- 281. 10) X 10- 6 ) and are characterized by depletion in LILE, enrichments in HFSE and LREE ((La/ Yb)N is 3. 70- 29. 40) coupled with slightly negnative Eu anomaly (0. 66-1. 14 with an average of 0. 88). The high SiO2 /AlzO3 (5. 04-77. 28 with an average of 22. 30) implies the high grade of maturity. The wide ranges of ICV (0. 61- 2. 13 with an average of 1. 21) and high CIA ( 82. 13 - 91. 68) indicate that the source rocks contain recycled ancient sediments and first-cycle materials, which have experienced high degree of chemical weathering and alteration in the heat and humid climate environment of tropical or subtropical zone. Integrated with geochemistry, elastic zircon U-Pb geochronology, paleogeography and tectonic evolution, it is suggested that Lower Devonian Lianhuashan Formation is deposited in passive margin, and its provenance may be Dayaoshan-Damingshan area in the north, and Yunkai area in the south. The source rocks of Lower Devonian Lianhuashan Formation mainly comprise Cambrian Huangdongkou Formation, and minor Neoproterozoic sedimentary rocks of Cathaysia block and the granitoids formed in Kwangsian orogeny (470-435 Ma).

Background——China’s highway facilities construction continue to be improved. However, there is little literature to evaluate the impact of highway facilities construction on regional forest resource management quality, which cannot provide effective decision-making reference for the formulation of forest quality improvement strategies. Methods——Based on the balanced panel data of 30 provinces and cities from 1993 to 2018,the panel data model was used to evaluate the impact of highway facilities construction on the quality of regional forest resources management. At the same time, we examine whether the highway facilities construction has an indirect impact through the three mediating variables of non-agricultural employment opportunities, the development of forestry secondary industry and the development of forestry service industry. Results——First, the coefficients of highway facilities construction on forest unit area accumulation and plantation unit area accumulation are 8.057 and 10.795,respectively, indicating that highway facilities construction has a significant positive effect on the improvement of regional forest resource management quality, which means that highway facilities construction can significantly improve the regional forest resource management quality. Secondly, the construction of highway facilities improves the growth of forest unit area accumulation by promoting the non-agricultural employment of rural labor force, the development of forestry secondary industry and service industry, and the indirect influence coefficients are 81.921,7.918 and 165.634,respectively. However, there is no indirect impact on the plantation unit area accumulation by promoting the non-agricultural employment of rural labor force, the development of forestry secondary industry and tertiary industry. Third, rural highway construction can significantly promote the growth of forest unit area accumulation (165.634) and plantation unit area accumulation (211.610). Primary highway construction can significantly promote the growth of forest unit area accumulation (7.918) and plantation unit area accumulation (10.958). Highway construction can only significantly increase forest unit area accumulation (81.921). Conclusions and Discussions——The construction of highway facilities has a significant promotion on the improvement of regional forest resource management quality. The construction of highway facilities promotes the growth of forest unit area accumulation by promoting the non-agricultural employment of rural labor force, the development of forestry second and service industry. Rural highway construction has a positive impact on forest unit area accumulation and plantation unit area accumulation. However, highway construction only has a positive impact on forest unit area accumulation, and primary highway construction only has a positive impact on forest unit area accumulation and plantation unit area accumulation. Based on the research results and conclusions, the following recommendations are proposed: First, the central and local governments are expected to improve traffic infrastructure conditions and take it as an important public policy that supports important forestry development, continuing to increase the density of highways, primary and rural roads. Second, the governments at all levels are supposed to accelerate the elimination of obstacles to restricted rural labor transfer and ensure the free transfer of rural surplus labor. At the same time, they should continue to improve the forest land transfer system and facilitate the transfer process. They also can encourage and promote the transfer of rural idle forest land, and try to avoid the situation of forest land abandonment or poor tending. Third, local governments are required to correctly address the relationship between forest protection and economic development, optimize timber industry support policies, promote the reform of “delegating power, improving regulation, and upgrading service” related to the wood industry, create a good industrial development environment, and promote the development of the second and tertiary industries of regional forestry.
