The results showed as follows:(1) the de-farming index of 479 investigated farm households is 79.21% with per capita area of de-farming slope farmland of 0.205 hm~2,per capita grain yield loss resulted from de-farming slope farmland of 74 kg and per capita allowance of 171 yuan from the government in 2003;(2) the de-farming allowance from the government has a bigger influence on a poor household,and if an allowance from the government would be stopped,the re-exploitation of partly de-farmed slope farmland is possible;(3) in 2003,per capita cash income of 479 investigated farm households is 1 492 yuan,and its sources mainly from floating employment,selling grain and greenstuff,de-farming allowance,selling products of domestic livestock and poultry and dealing dicker etc.;(4) in a few coming years,those employments of stable and higher earning will be firstly selected by farmers,and high expected value agriculture or rural commerce are going to become the leading livelihood of a good few farmers with some fund or skill.

结果表明：被调查农户人均退耕坡地0.205 hm2，退耕指数达79.21%；2003年479农户因退耕导致的粮食减产量人均74 kg，得到政府补贴人均171元；退耕补贴对贫困农户的影响程度较大，停止退耕补贴后存在反垦可能性。2003年被调查农户人均现金收入1492元，主要来源于外出打工、卖粮菜、退耕补贴、卖畜禽产品和做小生意等。未来几年，能获得稳定收入且报酬相对较高的行业是农民谋生的首选，有资金积累或一定技能的农户正在将生计转向高附加值农业或第三产业。

This research design each intersection offset by relative offset, and derive a "the expected value of progressive intersection number model". This research is for the sake of improving the traditional bandwidth method which is unable to accord with progression demand of every intersection to assign the progression ability effectively, and know the vehicles' real progression ability in the arterial system.

由於群组划分后各子系统路口时差以「绝对时差」进行设计，将无法直接进行相异周期之群组间路口时差最佳化求解，本研究遂以「相对时差」进行各路口间时差设定，并推导一「续进路口数期望值」模式，以改善传统绿灯带宽法无法依据各路口续进方向之交通需求量，有效分配各路口双向续进能力，且无法由绿灯带宽得知系统内车辆真实的续进能力之问题。
