吉林珲春自然保护区考察纪事

吉林珲春自然保护区位于图们江下游的吉林省珲春市境内,地处中、俄、朝三国的边境。保护区成立于2001年10月22日,总面积为88913公顷,其中核心区面积为49581公顷,主要保护对象为东北虎、远东豹及图们江下游的湿地。由于该区三国间东北虎、远东豹野生种群的迁移与联系,因而对虎豹的保护具有十分重要的意义。     

图们江流域耕地畜禽粪尿承载现状分析

为估算畜禽粪尿产生量和畜禽粪尿耕地承载量,并对畜禽粪尿耕地承载现状进行风险评价,试验收集分析了2013年图们江流域各类畜禽养殖数量。结果表明:2013年图们江流域畜禽粪尿年产生量为3 304.1 kt,畜禽粪尿耕地承载量为8.64 t/hm2,预警值为0.29,畜牧业生产尚未对环境产生影响;但在图们江流域的8个市(县)中,敦化市、汪清县和安图县畜禽粪尿产生量相对较高,故在图们江流域要因地制宜地结合不同地区畜牧业环境现状开展畜牧生产。

吉林省图们江区域非洲猪瘟防控要点分析

边境区域的动物疫病防控工作是决定能否阻断境外动物疫病传入的关键。本文对图们江区域的生猪养殖生物安全水平、防疫主体意识、生猪管理、流通调运和屠宰环节的情况及防控措施进行了分析,指出了养殖环节生物安全条件差、流通环节疫病传播风险高、屠宰环节消毒自检水平低以及人员力量不足等防控难点。这提示应着力提升养猪场户生物安全水平,严格监管生猪调运、强化运输车辆管控,加强屠宰环节监管,强化防疫队伍建设、健全防疫设施,以期为边境地区非洲猪瘟疫情防控提供借鉴。     

Heartworm in dogs in Canada in 1983
