In China, crop strews and energy crops are the main resource of bioenergy under the condition of secure food safe. There are lots of resource of crop strew, and only the main tree food crop can produce about 0.5 billion ton strew, which can maintain soil carbon and was used as the resource of bioenergy. In addition, there are about 0.1 billion hm2 waste hills and and that is suitable for farming or forestry can be used for the development of agriculture and forestry energy.

在保证粮食安全的前提下，农作物秸秆和能源作物则是生物质能的重要原料，我国农作物秸秆资源丰富，仅三大粮食作物每年就可以产生5×10~8t左右的秸秆，除了部分还田以保持土壤碳含量外，尚有可用于生物能源的部分，此外我国尚有近1×10~8 hm~2宜农、宜林荒山荒地，可用于发展能源农业和能源林业，而且我国能源农林业物种资源非常丰富，农业主要有木薯、甘蔗、甜高粱、油菜、花生、向日葵等，林业有漆树科的黄连木，无患子科的文冠果，大戟科的小桐子，山茱萸科的光皮树等，以此为原料可以进一步加强我国的生物液体燃料等的生物质能利用方式。

A definition of crop condition can be defined by its individualities and group characteristics. Two models were developed for crop condition assessment and diagnosis based on vegetation index and crop surface temperature.

该文以冬小麦为例，根据实地调查与北方数省的资料，用作物的个体与群体特征定义作物长势，讨论了遥感监测的可能性，提出了基于植被指数与植被表面温度的长势遥感监测的评估模型与诊断模型的概念与算法。

To detect the position of crop-rows, a method based on Hough transform and connected component labeling was put forward. First, a true color image of field crops was processed with gray histogram and OSTU respectively. Then the noises in the image were eliminated by means of eight connected component labeling according to their areas. The centroid coordinates of each labeled crop were computed after the second labeling, through which the center line of the crop-row was regressed by Hough transform. Experimental results show that the method is effective.

该方法分别用直方图法和最大类间方差法二值化图像后，经过8连通区域标记后据其面积属性去除噪声，然后再经一次标记后找出各标记作物的重心点坐标，最后通过Hough变换检测过重心点的直线，即到得到过作物行的中心线，试验结果表明了该方法的有效性。

Dong Feng county pushs policy of rural industry structural adjustment actively, below the premise of crop of main stable grain, according to the demand of benefit and market, each villages and towns enlarged the area of the economic crop such as melon dish, oil plants, beet, fruit appropriately, expand stock raising production energetically, make full use of existing commissariat straw is changed, develop ox, pig, birds to wait energetically, crop of 7 old economy and cultivate birds advocate the economic pattern that produces a division already formed embryo.

东丰县积极推进农村产业结构调整政策，在基本稳定粮食产量的前提下，根据效益和市场的需求，各乡镇适当扩大了瓜菜、油料、甜菜、水果等经济作物的面积，大力发展畜牧业生产，充分利用现有的粮食秸秆转化，大力发展牛、猪、禽等，七大经济作物及畜禽主产区的经济格局已形成雏型。
