Dayishan granite, a significant metallogenic-rock body located in Shaoyang-Chenxian tectonomagmatic belt of hunan province, was controlled by 'Dayishan-type' fault pattern. Based on the study of tectonic setting and geological features of the grantie, it is concluded that the tectonic system controlling magmatic emplacement is a shear folded-fauted zone which resulted from NW-trending convergent strike-slip faulting. The close relationship between the temporal-spatial distribution, emplacement mechanism of Dayishan granite and the strike-slip faulting is detailed.

Based on the statistical method and the historical evolution of meteorological sta- tions, the temperature time series for each station in hunan province during 1910-2014 are tested for their homogeneity and then corrected. The missing data caused by war and other reasons at the 8 meteorological stations which had records before 1950 is filled by interpola- tion using adjacent observations, and complete temperature time series since the estab- lishment of stations are constructed. After that, according to the representative analysis of each station in different time periods, the temperature series of hunan province during 1910-2014 are built and their changes are analyzed. The results indicate that the annual mean temperature has a significant warming trend during 1910-2014 and the seasonal mean temperature has the largest rising amplitude in winter and spring, followed by autumn, but no significant change in summer. Temperature variation over hunan province has several sig- nificant warm-cold alternations and more frequent than that in whole China. Annual and seasonal mean temperatures except summer and autumn have abrupt warming changes in the recent 100 years. The wavelet analysis suggests that the annual and four seasonal mean temperatures in recent 100 years have experienced two climatic shifts from cold to warm.

[Objective] The aim was to research regional division of citrus production and development strategies in hunan province. [Method] According to Rural Statisti- cal Yearbook in hunan province during 2002-2011, Citrus in hunan province were divided into three production regions, namely, superior region, sub-superior and non- superior region. On the base of the divisions, the ecological regionalization and brand strategy, Optimization of regional distribution and developing strategy were proposed, with consideration of avoiding frozen zones, in this paper. [Result] Fresh and processing bases of mandarin orange （*** Marc）, and specialty industries of seedless ponkan（*** Blanco）, Bingtang orange （*** Osbeck Bing- tangcheng）, Dayongjuhuaxinyou （Cgrandis （L.） Osbeck Dayongjuhuaxinyou） and An- jiangxiangyou （*** （L.） Osbeck Anjiangxiangyou） should be constructed, where fresh fruit is dominant, supplemented by canned fruit and juice. Industry belt of sat- suma orange, fresh or processing food, is mainly built, for proportion of early and earlier ripe satsuma orange is over 50% of total yield in Xiangzhong citrus zone; in- dustry belt of excellent fresh navel orange and processing sweet orange should be highlighted in Xiangnan. [Conclusion] The research provides references for decision- making for governments, especially on optimization of citrus production regions and development of citrus industry.

ln the research, an empirical analysis was performed on production per-formance and influential factors of rice in Changsha County and Liling City. The re-sults showed that production scale has been closely linked to age and education level of farmers. The larger scale, the higher comprehensive performance, but rele-vant efficiency tends to be lower. Sowing area and yield per unit area are major in-fluential factors of production performance of double-cropping rice, but the rest influ-ential factors are different upon production scale. Final y, developmental strategies are proposed for development of double-cropping rice.

[Objective] This paper aimed to investigate the agglomeration and fluctuation situation of economic crop production in hunan province and to propose related development countermeasures. [Method] With agglomeration index and fluctuation index as main indicators, the agglomeration and fluctuation situation of the production of seven major economic crops in hunan province in recent decade was studied. [Result] The agglomeration index of sown area and yield of seven major economic crops in hunan province showed decreasing orders of ramie 〉 cotton 〉 tobacco 〉 rape〉 citrus 〉 tea 〉 vegetables, ramie 〉 cotton 〉 tobacco 〉 tea 〉 rape 〉 citrus 〉 vegetables, respectively; the fluctuation index of sown area and yield showed decreasing orders of ramie 〉 citrus 〉 vegetables 〉 cotton 〉 tea 〉 rape 〉 tobacco, citrus 〉 ramie 〉 tea 〉 cotton 〉 rape 〉 tobacco 〉 vegetables, respectively. In addition, stable regions, relatively stabte regions and fluctuation regions of sown area and yield in various main producing areas were identified, and corresponding development countermeasures were proposed. [Cenclusion] The key to accelerate the development of major economic crop production in hunan province is further improving the agglomeration level of vegetable, citrus, rape and tea production and focusing on maintaining the stability of citrus, ramie and cotton production in main producing areas.
