Multi-sectoral Participatory Urban Forestry Development in Philippines Metropolitan Manila     

DONOSO Leonito Acosta 《中国林业科技(英文版)》2005,(1)

The Luntiang Kamaynilaan Project (Metro ManilaGreening Project) launched in 1988 planted trees inmajor thoroughfares, center islands, school premisesand other idle public lands, was basically a governmenteffort. When the funds ran out, the project also fizzledout. In both projects however, it is evident that the keyfactor is peoples participation.Gaining lessons from the past two projects, thegovernment established a collaborative effort ofgovernment and non-government organizations.

现代畜牧业课题组 《中国畜牧杂志》2006,42(20):24-28

世界各国由于自然经济条件差异较大,在畜牧业现代化过程中逐步形成了不同的模式和道路。国外现代畜牧业的模式有:现代草地畜牧业、大规模工厂化畜牧业、适度规模经营畜牧业和集约化经营畜牧业。那么,我国现代畜牧业的模式应该是什么?  相似文献   

刺槐抗旱造林技术的研究   总被引：2，自引：0，他引：2  

鲁子瑜  郭鹏 《陕西林业科技》1993,(4):17-22

在不同类型区及不同立地条件下，研究了提高剌槐成活率和生长量的抗旱造林技术。结果表明，采用径流集存、吸水剂蘸根、覆膜覆草及幼林地少量施肥技术，均可显著提高剌槐造林成率与生长量，提高幅度为２．０％－８．９％和１４．５％－８７．５％。采用混草技术可增收可观的优质牧草，经济效益和生态效益显著。  相似文献   

山洪对房屋的破坏及防患     

封尚忠  谢艳妮 《中国农村水利水电》1993,(6)

山洪对房屋的破坏随着生态环境的恶化而加剧,其损失又随人民生活水平的提高而增加。防患房屋遭受山洪破坏刻不容缓。本文客观地总结了山洪破坏房屋具有的区域性、多样性、毁灭性特征,通过分析房屋遭受山洪破坏的沉痼陋习,初步揭示了山洪惩罚人为性大失误的沉痛教训,进而提出防患山洪破坏房屋要非工程措施与工程措施相结合,运用社会、经济、法律的手段,加以减灾引导,加强建房管理,采取开撇水沟、挖水平槽、刨鱼鳞坑、砌护坡墙、打挡水桩等直接有效的工程措施,加速隐患补救,实现减灾目的。  相似文献

Prognostic factors in cats with chronic kidney disease     

King JN  Tasker S  Gunn-Moore DA  Strehlau G;BENRIC 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》2007,21(5):906-916

BACKGROUND: Chronic kidney disease (CKD) is a common cause of morbidity and mortality in cats. HYPOTHESIS: Some baseline variables are associated with shorter survival times in cats with CKD. ANIMALS: Client-owned cats. METHODS: Cats with CKD with initial plasma creatinine concentration > or =2.0 mg/dL and urine specific gravity (USG) < or = 1.025 were recruited into a prospective clinical trial that compared benazepril with a placebo. We describe baseline variables in 190 cats and their influence on renal survival time in the placebo group (95 cats), which was followed for up to 1,097 days. Renal survival time was defined as the time from initiation of therapy to the need for parenteral fluid therapy, euthanasia, or death related to renal failure. RESULTS: Of the 95 cats treated with a placebo, 58 were censored and 37 reached the renal survival end point (died, n = 0; euthanized, n = 17; parenteral fluids, n = 12; parenteral fluids followed by euthanasia, n = 8). Increased plasma creatinine concentration, increased urine protein-to-creatinine ratio (UPC), and increased blood leukocyte count were significantly (P < .01) associated with a shorter renal survival time and were independent risk factors. Increased concentrations of plasma phosphate or urea, and lower blood hemoglobin concentration or hematocrit were significantly (P < .01) associated with a shorter renal survival time and were dependent risk factors, because they also were significantly (P < .01) correlated with plasma creatinine concentration at baseline. CLINICAL IMPORTANCE: Several variables were significantly associated with a shorter renal survival time in cats with CKD.  相似文献
