    摘要:

    在1993—2012年湖北省各縣（市,、區(qū)）水稻生產(chǎn)實(shí)際狀況,、氣象資料,、地形等多種數(shù)據(jù)的支持下,，使用GIS技術(shù)建立數(shù)據(jù)庫,。結(jié)合中稻生長發(fā)育規(guī)律，計(jì)算中稻光合,、光溫,、氣候、耕地生產(chǎn)潛力及增產(chǎn)潛力,、增產(chǎn)空間,，將增產(chǎn)潛力劃分為5個(gè)等級區(qū)，繪制了相應(yīng)的圖表,，進(jìn)一步研究了湖北省中稻不同種植區(qū)域?qū)ψ匀毁Y源的利用現(xiàn)狀及開發(fā)前景,。湖北省中稻增產(chǎn)潛力巨大，理論值達(dá)1187.8萬t,，限制增產(chǎn)潛力的主要因素是耕地和氣候,。

    Abstract:

    Based on researches of light-temperature production potential, availability and regional planning of rice in Hubei province using GIS method, this paper reported the establishment of GIS based database by combination of mechanism method and experience approach, with the support of data of sub counties’ (cities, districts) rice actual production, meteorological data, terrain and etc. in Hubei province between years 1993—2012. The potential productivities of light, temperature, climate, arable land, yield-increasing potential and potential increase space were calculated by considering rules of production and development of middle-season rice. The yield potential was divided into five districts and the charts were drawn respectively. Natural resources and utilization status in different middle-season rice growing regions of sub-counties and cities in Hubei province were investigated further. The potential yield of middle-season rice in Hubei province is great and the theoretical value can reach 11877957 tons. The main limiting factors of potential yield are the arable land and the climate. The results of this study and the established database will provide valuable referees for guidance and plan of rice cultivation, industrial restructuring and implementation of high technology project in Hubei province.
