It has relatively high contents of REE (w(∑REE) = 149. 3×10-6) and unmarked LREE enrichment over HREE (wn (La)/wa (Yb) = 6. 99). Eight analysed zircon grains yield a well-defined discordia with an upper intercept of 3. 65 Ga. Some of the data points give an important in formation of more ancient zircon existence in the rock. The rock shows unusually low ε(Nd, 3. 8 Ga) values of - 1. 15 to -1. 24 and large tDM age of 4. 15-4.16 Ga. The geological significance of the discovery is briefly discussed in this paper.展开更多

The results showed that,due to scale effect,the drainage of three important industrial wastewater pollutants(COD,NH3-N and petroleum) increased 8505t,671t and 384t,respectively,and due to structure effect,those pollutants drainage increased 3996t,174t and 120t from 2001 to 2006. While due to technological effect,the drainage of COD,NH3-N and petroleum reduced 4452t,458t and 331t,and due to cross effect,those pollutants drainage reduced 7270t,575t and 476t simultaneously. Meantime,the relationships between household consumption structure and domestic sewage discharge were analyzed,and domestic sewage discharges in different income levels were also compared. The results showed that,the domestic sewage discharges would increase 376t with 1000 yuan(RMB) increased in the traffic and communication consumption,and they would be 344t,219t,428t,1873t,respectively,in housing consumption,food consumption,medical consumption,miscellaneous commodity consumption. The proportion of domestic sewage discharge increased for high income residents significantly,but reduced for lower income residents. The industrial wastewater pollutants drainage tends to be reduced by technical progress,while domestic sewage discharge will be a more important factor for urban water environment quality.展开更多

I take Anshan City in Liaoning Province as the study area which has its own particularity in terms of protecting farmland. Based on the prediction of population, coupled with the relevant data concerning farmland area, the per unit area yield of grain, the prediction and analysis of the balance of supply and demand of farmland in Anshan City are conducted. The results show that in the year 2010, the maximum supply amount of farmland that the city can offer is 239 000 hm2, and in the year 2020 the maximum supply amount of farmland that the city can offer will be 238 000 hm2; in the year 2010, the maximum demand amount of farmland is 204 186.02 hm2, and in the year 2020 the maximum supply amount of farmland will be 226 409.61 hm2. So the supply amount of farmland that the city can offer can meet the need of grain production objective. Some problems concerning farmland protection are pointed out in order to provide beneficial exploration of the farmland protection based on the model of food security.展开更多

According to requirements of Notice of the General Office of the People's Government of Anhui Province on Implementing the Confirmation and Registration of Ownership of Rural Collective Land,in order to integrate urban and rural development and safeguard the rights and interests of farmers,since January 2010,Ma'anshan Municipal Government has made an overall deployment in the whole city to carry out the confirmation and registration of rural collective land. However,complex property situation of the collective land and the problems of existing registration system have brought about many problems. Through the research and analysis,we came up with recommendations for improving the registration of rural collective land.展开更多
