用好政策突破瓶颈     

蒋金红 《浙江国土资源》2005,(7):18-19

保护耕地是我国的一项基本国策,实行宏观调控是党中央国务院作出的重大决策,控制建设总量是实施宏观调控的重要手段.加快发展是党执政兴国的第一要务.金华市去年人均GDP达到2600美元,正处于工业化加速推进时期,省委省政府又把金华作为浙江中西部中心城市来培育,各项建设都需要有一定的土地资源予以保证.保护耕地和保障用地是一对矛盾.如何解决这一对矛盾,突破用地瓶颈,需要我们树立科学的发展观,深刻领会国家实行宏观调控的精神实质,用足用好省出台的有关政策,做好以下几方面工作.  相似文献   

土地征用中留地安置政策有待完善     

王少荣  刘丽明 《浙江国土资源》2004,(4):38-39

随着城市建设的快速发展,全面建设小康社会目标的实施,土地是一个必不可少的物质条件,没有一定数量的土地提供作依据,就很难有效地实现城市扩容和现代化建设.因此,有计划有目的地合理征用一部份土地,是城市化和现化化建设的需要.  相似文献

Silicon limitation on primary production and its destiny in Jiaozhou Bay, China——Ⅳ：Study on cross-bay transect from estuary to ocean   总被引：1，自引：0，他引：1

The authors analyzed the data collected in the Ecological Station Jiaozhou Bay from May 1991 to November 1994, including 12 seasonal investigations, to determine the characteristics, dynamic cycles and variation trends of the silicate in the bay. The results indicated that the rivers around Jiaozhou Bay provided abundant supply of silicate to the bay. The silicate concentration there depended on river flow variation. The horizontal variation of silicate concentration on the transect showed that the silicate concentration decreased with distance from shorelines. The vertical variation of it showed that silicate sank and deposited on the sea bottom by phytoplankton uptake and death, and zooplankton excretion. In this way, silicon would endlessly be transferred from terrestrial sources to the sea bottom. The silicon took up by phytoplankton and by other biogeochemical processes led to insufficient silicon supply for phytoplankton growth. In this paper, a 2D dynamic model of river flow versus silicate concentration was established by which silicate concentrations of 0.028–0.062 μmol/L in seawater was yielded by inputting certain seasonal unit river flows (m³/s), or in other words, the silicate supply rate; and when the unit river flow was set to zero, meaning no river input, the silicate concentrations were between 0.05–0.69 μmol/L in the bay. In terms of the silicate supply rate, Jiaozhou Bay was divided into three parts. The division shows a given river flow could generate several different silicon levels in corresponding regions, so as to the silicon-limitation levels to the phytoplankton in these regions. Another dynamic model of river flow versus primary production was set up by which the phytoplankton primary production of 5.21–15.55 (mgC/m²·d)/(m³/s) were obtained in our case at unit river flow values via silicate concentration or primary production conversion rate. Similarly, the values of primary production of 121.98–195.33 (mgC/m²·d) were achieved at zero unit river flow condition. A primary production conversion rate reflects the sensitivity to silicon depletion so as to different phytoplankton primary production and silicon requirements by different phytoplankton assemblages in different marine areas. In addition, the authors differentiated two equations (Eqs. 1 and 2) in the models to obtain the river flow variation that determines the silicate concentration variation, and in turn, the variation of primary production. These results proved further that nutrient silicon is a limiting factor for phytoplankton growth. This study was funded by NSFC (No. 40036010), and the Director's Fund of the Beihai Sea Monitoring Center, the State Oceanic Administration.  相似文献
