The concentrations of nine metals (Cd, Cr, Cu, Ni, Mn, Pb, Zn, Fe, and Al) in surface sediments from 14 sampling sites in Shantou Bay were determined in order to understand current metal levels and spatial distribution due to the rapid development of the Shantou Special Economic Zone. Results showed that metal concentrations in surface sediments varied from 0.31 to 1.74 mg kg(-1) for Cd, 35.98 to 74.19 mg kg(-1) for Cr, 24.43 to 79.24 mg kg(-1) for Cu, 428.45 to 809.87 mg kg(-1) for Mn, 16.91 to 31.51 mg kg(-1) for Ni, 35.59 to 64.84 mg kg(-1) for Pb, 84.91 to 246.51 mg kg(-1) for Zn, 2.93 to 3.93% for Fe, and 5.25 to 9.28% for Al. Although all metal concentrations in sediments meet Chinese National Standard Criteria for Marine Sediment Quality, both enrichment factor (EF) and geo-accumulation index (Igeo) show Pb and Cd pollution existed in the upper and middle bay, and pollution of other metals is also recorded in some sites depending on the sources; river input, sewage discharge, and port activities are the main sources of pollutant to the bay.

A design project of 16 bit RISC MCU with full scan structure by the tool of SYNOPSYSTM DFT COMPILER. The flip-flops can be linked into the chains; the memory modules in the MCU were tested by the technology of BIST; and the circuits were tested by the test vectors by ATPG. The chip test circuit include 8 chains, and cover rate can reach at 99.20%.

Environmental Geo-technology involves not only the ecology but also the basic theory of environmental economics, management, control and monitoring aspects, so it is the ultimate goal that closes to the service the strategic policy of sustainable development of human economic system. Eco-tourism is a new form of tourism which is using a sustainable development as its guiding ideology, and it is the construction of ecological city of Shenyang is an important aspect. The paper combined with the request of Shenyang’s detailed condition, and then given some suggestions to improve the protection measures of Ecological environment by using geo-technology so that it can lead eco-tourism of Shenyang to the road of sustainable development.
