Grey Relational Analysis on Industrial Structure of Animal Husbandry in Inner Mongolia

This paper introduces the connotation of grey relation and computation method of grey relational degree. Based on grey relational model and relevant data during 2003- 2012,this paper performs an empirical analysis of the internal structure of agricultural economy and the internal structure of animal husbandry in Inner Mongolia. The results show that animal husbandry and farming are two important sectors of agricultural economy in Inner Mongolia,and within animal husbandry,the influence of dairy cow,mutton,beef and goat wool production is most obvious. Based on this,this paper puts forth the following recommendations: stabilizing the dominant position of farming and animal husbandry in the agricultural economy; continuing to adjust and optimize the internal structure of agricultural economy; reasonably and guide the development of various industries within animal husbandry.

Geological evaluation for the carbon dioxide geological utilization and storage(CGUS)site:A review

Carbon dioxide(CO_(2))geological utilization and storage(CGUS)is the key link of CO_(2)capture,utilization,and storage(CCUS).The accurate characterization of the geological body structure is a vital prerequisite of CGUS.This paper gives a review of the multi-scale three-dimensional geological structure characterization and site selection of CO_(2)storage.It shows that there is a lack of systematic and high-precision methods for transparency characterization of multi-scale three-dimensional engineering geological structure and hydrogeological structure of a CO_(2)storage site.There is no clear understanding of the fracture evolution and gas-liquid migration process of multi-scale geological body structure under the disturbance of CO_(2)injection.There is a lack of sufficient quantitative methods for the dynamic evaluation of CO_(2)geological storage potential.The geological suitability evaluation method for site selection of CO_(2)storage is rough and has poor applicability,which is difficult to satisfy the urgent needs of CGUS site selection in the whole process of CO_(2)sequestration industrialization in the future.Thus,it is required to conduct studies on the transparency characterization of geological body structure and intelligent site selection for CO_(2)storage,which is of great importance for CGUS engineering practice.
