Based on the plant level data from the First National Census of Basic Units, the Second National Census of Basic Units, and the First National Economic Census of china, this paper ex- amines the geographical agglomeration of chinese manufacturing industries at a more disaggregated level both by industrial classi-fication and spatial unit analysis. Applying the agglomeration index proposed by Maurel and Sedillot, studies show that the most agglomerated industries are resource-intensive, and capital and technology intensive while industries demanding localized inputs or serving localized markets or favored by local governments are fairly dispersed. The more disaggregated industries are more spa- tially agglomerated. At the finer spatial scale, industries are more dispersed. Results indicate that within-county spillovers are stronger than nearby-county spillovers, and within-prefecture spillovers are stronger than nearby prefecture spillovers. Local- ized spillovers are still quite substantial at a range beyond that of counties. Comparing the agglomeration index of chinese manu- facturing industries in 1996, {3.01 and {3.04, agglomeration seems to be a general tendency. Results also indicate that some industries have experienced remarkable changes in their levels of agglom- eration in the period 1996–{3.04.

Greenhouse Gas Emissions from Northeast china Rice Fields in Fallow Season

Pedosphere 2007年第5期17卷 630-638页

作者： LIANG wei SHI Yi zhang {2. YUE Jin {2.NG Guo-Hong institute of Applied Ecology Chinese Academy of Sciences Shenyang 110016 （China） Graduate School of the chinese academy of sciences Beijing 10005g （China） College of resources and Environment Huazhong Agricultural University Wuhan 430070 （China）

CH4, N2. and CO2.emissions from northeast chinese rice fields were measured in the fallow season （November to March） to investigate the effects of freezing-thawing on the emissions. Both CH4 emission from and atmospheric CH4 oxidation by the soil occurred, but the flux was small. During the fallow season, rice fields acted as a minor source of atmospheric CH4, which accounted for about 1% of the CH4 emission during the rice growing period. The field was also a substantial source of atmospheric N2., which ranged between 40 to 77 mg m-2.and eu=counted for 40%-50% of the annual N2. emission. The largest N2. flux was observed in the thawing period during the fallow season. Laboratory incubation tests showed that the largest N2. flux came from the release of N2. trapped in frozen soil. Tillage and rice straw application （either mulched on the soil surface or incorporated in the soil） stimulated the CH4 and CO2.emissions during the fallow season, but only straw application stimulated N2. emission substantially.
