洞庭湖湿地景观特征与农业产业化模式研究

洞庭湖湿地是我国最大的淡水湖泊湿地景观生态系统之一,湿地农业资源丰富,农业开发历史悠久,生产化水平较高,是我国重要的农业商品基地。由于过去长期受传统耕作方式的影响,农业产业化程度较低,农业经济发展缓慢;本文根据洞庭湖湿地景观特征,对洞庭湖湿地农业资源和湿地农业开发现状进行了评价和分析,指出了湿地农业开发中存在的问题,提出了洞庭湖湿地农业产业化开发利用模式,以实现洞庭湖湿地农业经济的飞速发展。

RESEARCH ON THE LANDSCAPE CHARACTERISTICS AND THE MODELS OF AGRICULTURAL INTEGRATION IN DONGTING LAKE AREA WETLAND

The Dongting lake area wetland is one of the largest fresh water wetland ecological systems in China. It has a very long history of agricultural exploitation, a relatively high agricultural production level and an important base of agricultural commodity in our country.Due to influence of traditioinal cultivation pattern in the past, the level of the agricultural integration is very low so as to affect the Dongting lake area economic development. Based on the landscape characteristics of the Dongting lake area wetland, the article is divided into three parts:there are lake and streamlet area and plain area and the low hills area around lake in Dongting lake wetland area. The Dongting lake area wetland agricultural resources and the present state of the wetland agricultural resources ex ploitation are evaluated and analyzed, and there are a lot of biological resources and the ex tensive water area resources and the multiple land resource. There are the relatively developed agricultural economy and the superior location.The problems of the wetland agricultural resources exploitation and utilization are pointed out that the wetland agricultural resources are not rational exploitation and utilization, the agricultural products are a low science and technology content and the marketplace information of the agricultural products is ineffective so that there is the low commerce development level of the agricultural products in Dong ting lake area. The agricultural integration is the only way out in order to increase the rate of the agriculture commodity in Dongting lake area. The development models of the wetland agricultural integration are put forward to that these are the agricultural integration models of the chief-enterprise impetus and the agricultural model of the intermediary com bination promoted and the agricultural model of the marketplace carried forward and the agricultural model of the science and technology propelled, achieving the purpose of the fast development of the agricultural economy in Dong ting lake area wetland and realizing the objective of the Dongting lake area agricultural modernization, benefiting the Dongting lake wetland agricultural resources sustainable development.
