This paper uses entropy to measure the resilience of Shandongs tourism economy, discusses its spatial pattern, and applies geographic detector and obstacle model to analyze its factors. The resilience of Shandongs tourism system is generally at a medium level, higher in Jinan, Qingdao, average in Yantai, Weifang, Linyi, Jining, and lower in northwest, southwest and southeast. It shows a “U-shaped” spatial pattern that Qingdao of high resilience and Jinan of relatively high resilience are connecting to southeast and east with medium resilience, the northwest is massively of low resilience. The spatial differentiation is mainly contributed by financial guarantee level (X1), resident consumption capabilities (X4), import & export level (X5). The chief obstacles against resilience are tourism major in university (D1),  tourism economy reconstructing capability (C2), and  tourism economy level (A2).

This paper, aiming at energy-saving-emission-reduction objective, establishes a low carbon optimized model of Hebei's energy consumption structure from economic growth, energy-saving, green-house gas emission control, energy resource abundance and technical advances, which is employed to optimize many objectives of low carbon energy consumption structure in 2020 based on Hebei's energy situation and planning. The premier energy consumption plan can not ensure the economic growth objective, the premier carbon reduction plan has higher energy consumption and lower feasibility in one-time power consumption objective, the premier energy intensity plan is a balance between energy saving and emission reduction, which makes sure the objectives of Hebei's “13th Five Years Plan” energy saving and economic growth with feasibility.

Tashan magma is a assemblage of ring ultra-unit intrusive formed of diversified magmas in Anlin area,Anyang to Lin County, northern Henan province. The early stage is diorite porphyry, quartz diorite porphyry, belonging to sodium calcium-alkaline magma; the late is aegirine augite syenite, aegirine augite-bearing alkaline syenite porphyry, alkaline granite, belonging to high-K alkaline magma. The magma comes from deep, a remelting by mantle and less crust. The magmatic activity is related to Taihangshan intercontinental orogeny in late Yanshanian period characterized by stretching structures, and to Anlin style skarn iron ore with strata-controlling features. Other ores related to Tashan magma includes gold, k-feldspar and blue asbestos.

This paper applies the green equivalent to establish a model to evaluate the land utilization structure in Qianjiang city, Hubei province, studies how to optimize the land utilization structure and to enhance the land system function, and how to make a rational distribution and intensive utilization of land resources in all areas, all industries and all units, offering a reference for the sustainable development of regional land resources.
