As to the series of drought, this study has expounded the necessity and urgency of human-land relationship regulation in drought control and disaster release, from the aspect of human factorsthe inharmonious relationship between human and land. Based on that, the main countermeasures of drought control and disaster release have been further explored, in order to provide references for the future drought control and disaster release in Yunnan.展开更多

To speed up the development of modern agriculture in CEDAs, this paper takes Suzhou City as an example from theories supporting modern agricultural development. It demonstrates agriculture in CEDAs plays an important role in adjusting supply of agricultural and sideline products, reserving rural labor employment, protecting ecological environment, increasing farmers income, and passing on agricultural culture. It contends that CEDAs should take reserving basic farmland as prerequisite; take adequate supply of primary agricultural products, protection of living environment, maintenance of agricultural landscape, and inheritance of farming culture as objectives; establish perfect modern agricultural system through firmly setting up modern agricultural value concept; increase local public finance input; increase agricultural functional value from technical and management levels, to realize increase of farmers income, promote sustainable development of agriculture, promote integrated urban and rural development, as well as harmonious development of human and nature.展开更多
