【农林牧渔业总产值】是以货币表现的农林牧渔业的全部产品总量和对农林牧渔业生产活动进行的各种支持性服务活动的价值。它反映一定时期内农林牧渔业生产总规模和总成果，是观察农林牧渔业生产水平和发展速度，研究农林牧渔业内部比例关系、农林牧渔业与工业、农林牧渔业与国家建设、人民生活比例关系的重要指标，同时也是计算农林牧渔业劳动生产率和农林牧渔业增加值的基础资料。

农林牧渔业总产值的计算,一般采用“产品法”,即凡有产品产量的，都按单位产品价格乘产量的办法求得每种产品产量的产值，然后相加求得各业的产值，最后各业相加求出农林牧渔业总产值。

【都市农业】是指在城市化地区，利用田园景观、自然生态及环境资源，通过农林牧渔业生产、农业经营活动、农村文化及农家生活，为人们休闲旅游、体验农业、了解农村提供场所，集农业的生产、生活、生态等功能于一体的产业。

【绿色农业】是指以获得国家认证的绿色农产品生产基地为场所，实施绿色农业工程，开发无污染、安全、优质的绿色农产品、有机农产品的综合高效产业。

【都市农业总收入】是指都市农业统计地理区域内各生产经营单位当年农业生产、加工本地农产品的价值量以及运输、批发零售本地农产品和观光休闲旅游农业的总收入。它是由农业生产产值、加工本地农产品产值、运输本地农产品总收入、批发零售本地农产品总收入和观光休闲旅游农业企业总收入组成。

【农业产业化】农业产业化是以国内外市场为导向，以经济效益为中心，通过自身的组织形式和运行机制，把分散的农户与某组织联成一体，众多的农户在该组织的带动下按同一标准进行统一生产，使一种或一类产品的生产在一个较大的区域内连成一片，形成较大规模，实现了农业由家庭分工向区域分工和社会分工的转变，形成了农户生产的专业化、农业布局的区域化、农产品生产的标准化和农业经营的规模化，将农业的产前、产中、产后诸环节有机地联为一体的经济运行方式。

【农业龙头企业】是指由区级或县级以上政府部门认定的，以农副产品生产、加工或流通企业为龙头，用合同契约关系或产权联结等多种形式，带动当地农户从事专业生产的经营组织。

【Gross Output Value of Agriculture】refers to the total vo-lume of products of farming,forestry,animal husbandry,and fishery and the value of various services supporting the production of far-ming,forestry,animal husbandry and fishery in monetary terms, which reflects the total scale and total results of farming, forestry, animal husbandry, and fishery production during a given period of time.It is an important indicator to observe the production level and development speed of farming,forestry, animal husbandry,and fishery,to study the internal structure of farming, forestry,animal husbandry,and fishery,and to review the relationship among farm-ing, forestry, animal husbandry,and fishery and industry, national construction and people's life.It is also the basic data to calculate the labor productivity and value-added of farming,forestry, anim-al husbandry,and fishery.

Generally,the gross output value of farming,forestry,animal husbandry, and fishery is calculated with the production approach, i.e.the gross output value of each single product is obtained by multiplying the output of each product by its price.Then the output value of each sector is obtained.Finally,the sum of output value of all sectors is equal to the gross output value of farming, forestry, animal husbandry,and fishery.

【Area of Regularly Cultivated Land】refers to farmland a-mong the total land resources which is exclusively used for farm-ing and is under regular cultivation with harvest in normal years. Included are currently cultivated land ,land that has been abandon-ed or put in idle for less than 3 years and could be re-used for cul-tivation at any time,and new-claimed land that has been put into cultivation for more than 3 years,Excluded are the land under tem-porary cultivation,land (large or small plots)that is claimed along river bends,lake sides or banks of reservoirs,as well as land that has been designated under the reen for Grainprograms of the state and provincial governments but is still temporarily under cul-tivation.

【Sown Area of Crops】refers to area of land sown or tran-splanted crops at the end of a production season.

The statistical year of sown area refers to area of land sown during the year (from Jan.1 to Dec.31)with a harvest of crops (in-cluding all those sown in the autumn and winter of the preceding year).

【Total Power of Agricultural Machinery】refers to total mechanical power of machinery used in agriculture, forestry, animal,husbandry and fishery,including machinery for ploughing,irrigation and darinage,harvesting,farm products process,transport,plant protection,animal husbandry,forestry and fishery and other agricultural machineries.

【Urban Agriculture】refers to industry that integrates agricultural production, life and ecology in urbanized area. This industry utilizes countryside landscape, natural ecology and environmental resources to provide places for leisure traveling, agricultural experience and understanding through production of agriculture, forestry, animal husbandry and fishery, agricultural operating activities, rural culture and life experience.

【Green Agriculture】refers to comprehensive efficient industry that implements green agriculture engineering and develops non-polluting, safe and high quality green agricultural products in the green agricultural production base that obtained national certification.

【Total Income of Urban Agriculture】refers to the total income of production and business enterprises in the statistical geographic area of urban agriculture. The income includes agricultural production of the year, magnitude of value of processing local agriculture products, transporting, wholesaling and retailing local agriculture products and the income of agricultural sightseeing and tourism.

【Industrialization of Agriculture】refers to an economical operation method that oriented by domestic and international market, and takes economic benefits as centre. This method unites the scattered farmer households to the organizations through its organizational forms and operating mechanism. The organizations lead numerous farmer households to product unified productions under the unified standard. The production of the same species can extend within a large region and have a large scale. This method achieves the agriculture transition from family division to regional division and social division. It forms a specialization of agricultural production, regionalization of agricultural distribution, standardization of agricultural products and scaled agricultural operation. This economical operation method dynamically links the agricultural pre-production, in-production and post-production to integration.

【Agriculture Leading Enterprises】refers to the enterprises that recognized by governments above district-level or country-level. The enterprises producing, processing and circulating agricultural and sideline products are the leading enterprises, and they can encourage local farmer households to work on professional production through contract, agreement or property right connection.
