Based on the method and principle of the tracing in the source of mineralization material from the stable isotope, we use the sulfur isotopic indexes from Wunugetushan, Kenshan, Bainaimiao,Inner Mongolia, and Chengmenshan area in Jiangxi, and try to use the characteristics of sulfur isotopic composition (δ~(34)S) to determine the causes of geochemical anomalies.

Therefore,the farmers in Dongting Lake reclamation region may resettle in Southern Xizang Region in order to guard Xizang and implement the strategy of "returning the cultivated land into the lake".

This paper introduces the essential situation and regional water resources character of the reclamation area and analyzes the existing problems and the utilization circumastance.

Estimating ecological value of reclamation area is of instructional meaning to quicken ecological construction,perfect new rur.

Flax is a main crop in the adjustment of agricultural planting structure in reclamation areas,2/3 of the total flax area in Heilongjiang Province was concen trated in these areas.

Implementation of grouting in the test area,left bank proves the feasibility of high pressure grouting in the stratum, which is featured by slim-size borehole,orifice-closed,and internal circulation,and the anti-seepage capacity after grouting.

Through analyzing the needs of the society for network engineering specialty talents, we present a construction scheme of the test area of innovative talents for network engineering specialty.
