This paper establishes a county domain development quality assessment index system by using Principal Component Analysis to analyze the major factors, which is used to comprehensively evaluate Zhejiang’s county domain development quality and its temporal spatial evolution. Economy, industrial structure, social wellness and resources are the major factors of county domain development quality. Zhejiang’s county domain development quality shows an SN & EW variance, high in the NE and low in the SW, displaying a mode of “core to margin”. As time goes by, the county domain with higher development quality is enlarging its concentrating space. This paper presents approaches to Zhejiang’s county domain comprehensive development from accelerating the ecological development of underdeveloped southeastern Zhejiang, intensifying the key cities’ driving force with high development quality in Hangzhou, Ningbo, Jinhua Yiwu, and Wenzhou Taizhou. Their surrounding counties shall be prepared to succeed industrial transfer, providing conditions for upgrading industry in core areas. Planning oceanic and continental economy achieves Zhejiang’s coastal cities’ economic development.

This paper selects Zhoushan's economic system to study its vulnerability and establishes an assessment index system from its sensitivity and response capacity，which employs entropy to give weights to each index.It uses TOPSIS to construct two modes in assessing vulnerability and barrier degree.The models are applied to analyze the evolution of Zhoushan‘s economical vulnerability and its influencing factors，with results showing arising vulnerability.The sensitivity prevails to its economical vulnerability.The main influencing factors lie in the contribution of the first industry in GDP，unit GPD energy consumption and dependence on foreign trade.The last two are the biggest barriers in reducing zhoushan’s economic vulnerability.

The western China to Qinghai-Tibet area covers Gansu, Qinghai, Xinjiang, Tibet and western Sichuan, where distributes lots of sedimentary basins hosting abundant oilshale resources. The oilshale resources reach to 195.263 billion tons in these areas, about 4.44% of the total in China, the oilshale potential is 193.039 billion tons, 28.82 of the total in China, indicating a big potential in these areas. The genesis of oilshale can be classified as sapropel , humosapropelic and humic, formed in lakes, marshes and lagoons, where the oilshale is quality, most more than 10% in oil-bearing rate. The oilshales are distributed in the upper Paleozoic, Mesozoic and Cenozoic, becoming younger southwards in oilshale formation ages. This paper, based on a prioritization of exploration targets, selects 9 target areas as most favorable areas, 7 as favorable areas, and 4 as sub-favorable areas.

Mining cities are facing a series of serious issues like massive poor, collective unemployment and deteriorating environment, which makes a fragile social system. This paper illustrates the frangibility of social system, establishes an indexes system model to assess the frangibility in five districts in Fuxin city from resources distribution, population structure, education level, sanitation, social order, social guarantee and logistic construction. The results imply a big difference in social frangibility among the districts, first in Xinqiu district, second in Taiping district and last in Xihe district. The paper discusses the major causes of the frangibility in Fuxin city.
