充分肯定我省土地整理开发工作取得的成效 在各级党委、政府的正确领导下,在省耕地保护和造地改田领导小组成员单位的大力配合支持下,我省土地整理和标准农田建设取得了显著成绩.至2004年底,全省通过土地整理等方式建成标准农田1194.38万亩,新增耕地达182.07万亩,为我省连续9年实现耕地占补平衡提供了重要保障.核拨土地整理折抵指标131.09万亩,使用折抵指标批准的耕地104.26万亩,占全部批准建设占用耕地179.27万亩的58%,大大缓解了我省建设用地计划指标严重不足的矛盾.同时,通过土地整理和标准农田建设,提高了耕地质量,改善了农业生产条件.通过农村居民点综合整治,改善了农村的交通环境、生态环境、生活居住环境,开辟了村级集体经济收入财源,壮大了村级经济,为村民办了一些实事、好事,既调动了基层干部的工作积极性,又增强了村级班子的凝聚力,促进了农村基层建设.  相似文献

Effect of Ploughing Depth on the Growth and Yield of Heracleum candicans： a Threatened Medicinal Herb and a Less-explored Potential Crop of the Himalayan Region     

Hemant K. Badola Jitendra S. Butola 《山地科学学报》2005,2(2):173-180

This paper examines the effect of ploughing depths （A -- 60 cm, B -- 45 cm and C -- 30 cm） on the growth and yield of Heracleum candicans Wall （Apiaceae）, a threatened medicinal herb of the Himalayan region. This less-explored plant is being suggested as a potential crop for the mountain agriculture. The study was carried out in an orchard in Himachal Pradesh, India at 2500 m altitude, for two successive growth years. During the first year, all plants remained in juvenile state; in the second year, nearly 65 % plants produced flowers only under 60cm ploughing depth. Among its morphological traits, plant height, collar diameter and aboveground flesh weight were found to be strongly correlated （P 〈 0.01） with the belowground biomass during the first year （r =0.968, 0.925 and 0.973, respectively） and during the second year （r=0.945, 0.928 and 0.775, respectively）. Increase in the ploughing depth was significantly correlated （P〈0.01） with all growth parameters, including the belowground dry weight, marketable portion of the produce. The belowground biomass （commercial yield; 16.28 Qt/hec） at depth A was about 2.6 and 4.7 times higher than those recorded at depths B and C, respectively. The results clearly justify the importance of deep ploughing and this paper strongly recommends it for economically sustainable cropping.  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   

我局是如何强化基层所建设的     

徐公立张存功  刘保恩 《河南国土资源》2006,(11):22-23

太康县位于豫东平原，是一个典型的农业大县、财政穷县。全县总人口131．9万人，其中农业人口115．8万人，耕地面积171．4万亩，人均耕地约1．3亩，低于全国人均耕地平均数。因而切实保护耕地，合理利用土地资源对太康经济发展至关重要。1999年，太康县将原属于乡（镇）管理的国土所上收，实现了县、乡土地管理机构垂直管理，并且在理顺体制和提高素质上狠下功夫，较好地发挥了基层国土资源所的作用。  相似文献

保护和集约利用开发区建设用地实现县域经济跨越发展     

张雅娟佟伟光  张艳荣 《黑龙江国土资源》2004,(4):35-35

近年来，由于受诸多因素的影响和制约，宾县没有突破以传统农业为主的经济发展格局，致使农业大而不全、工业弱小、第三产业不发达，与周边市县的发展差距不断加大。为了从根本上实现经济的跨越发展，从解放思想入手，在大调研、大考察、大讨论的基础上，确定了“工业强县、牧业富民、旅游带动、外力牵动”的经济发展思路。把招商引资，借外力发展壮大工业经济做为主攻目标和突破口，以工业经济的率先发展带动整个县域经济的快速发展。因此，借宾西镇的区位优势，辟建了宾西经济开发区。2002年9月，经  相似文献

刘胤汉  陆立新 《山地学报》1990,(1)

农业自然资源据其在农业利用过程中的地位可分为两类:一类是生成农业自然资源的环境,另一类为可资直接利用的自然生成物(即狭义的农业自然资源)。陕西秦巴山区自然环境的主要特点是:复合山体高峻庞大,地跨暖温带和北亚热带,垂直分异明显。区内有:森林、草场、野生生物、林特产与农作物等多种农业自然资源。据此,提出了本区农业自然资源的开发利用途径。  相似文献
