So the present study was taken to compare the differences in the mechanisms of dissipating excess light energy in cucurbit crops and to study the differences in both the ROS metabolism in root system and the photosynthesis among six cucurbit crops with different temperature tolerance growing at different root-temperatures. The main results are as follows: 1、The species specific response of three cucurbit crops with different heat-tolerance: warm-adapted cucumber, heat-tolerant sponge gourd and heat-sensitive figleaf gourd to diurnal changes in air temperature and irradiance intensity were investigated in a typical summer sunny day. Three cucurbit species were compared using parameters in gas exchange, chlorophyll fluorenscence, photon allocation and photosynthetic electron flux.

因此，本试验以温度敏感性不同的瓜类作物为材料，研究了夏季自然条件下不同物种间在耗散过量光能的主要机制差异；探讨了它们对不同根际温度在根系活性氧代谢及地上部光合作用等方面的生理响应差异，所取得的主要结果如下： 1、在夏季晴天条件下，三种温度敏感性不同的瓜类作物：喜温的黄瓜，耐热性的丝瓜与热敏感的黑籽南瓜在气体交换、叶绿素荧光、光能分配及光合电子流对一天中温度与光照环境变化的响应上存在物种间差异和日变化特征。

Because obvious differences in the coefficient between stomotal conductance and photosynthesis rate were found between C3 and C4 crops, and between terricolous and aquicolous C3 crops, the crop ecotype can be generally distinguished three types: C4, terricolous and aquicolous C3 crops.

由于该系数在C3作物和C4作物之间存在明显差异，C3作物中，陆生C3作物和水生C3作物也存在一定差异，因此作物的生态功能类型可以大体划分为3类：C4作物、陆生C3作物和水生C3作物。

General arithmetic frameworks of crop simulation model can be systemically classified by the crop variety, and then on the base of crops" general physiological-ecological process, it is divided into five modules. We synthetically epurate general arithmetic frameworks, covering crops" main dynamics of growth process, such as plant development stage and phenophase, photosynthesis, respiration, dry matter accumulation and partitioning , LAI, yield formation, et al, and introduce parameters to build different crops growth simulation general arithmetic.

根据作物的不同类型，对国内外作物生长模拟模型进行系统分类，再以作物的一般生理生态规律为基础，将作物生长模型划分成五大组成模块，通过系统地分析、综合，提炼作物生长模拟通用算法框架，涵盖了作物阶段发育和物候期、光合作用、呼吸作用、干物质积累和分配、叶面积指数、产量形成等主要的生长动态过程，并采用参数化建立了不同作物的生长模拟模型通用算法。

Strong comparative advantage crops late rice and cotton should be enlarged. Infirmness comparative advantage crops early rice, medium rice and rapeseed should be maintained. Strong comparative disadvantage crops soybean and peanut should be reduced.5 , Cropping systems were optimized by linear programming model.

通过测定奉新县主要衣作物在红壤丘陵区成本比较优势指数和单产比较优势指数，根据综合比较优势指导种植结构调整，得出晚籼稻和棉花具有&强比较优势&，应当适当扩大生产；早籼稻、中籼稻、油菜籽的成具有&弱比较优势&，应当维持原来的水平；大豆和花生具有&强比较劣势&，应该适当压缩生产。

The study revealed the characteristics of modern climate changes, which is warming in winters and dry in summers. The characteristics of the impact of climate change on overwinter crops, cool temperaturephilic crops and tropical crops in growth and development, planting area and suitable planting altitude, and yield and quality were analyzed systematically.

在揭示甘肃省现代气候变化基本特征是冬暖夏干的基础上，比较系统地综述了越冬作物、喜凉作物和喜温作物等8种主要农作物的生长发育、适生种植区高度和种植面积、产量和品质等对现代气候变化的响应特征。
