针对辽河三角洲大洼小三角洲部分的过度农业开发对野生动物生境的严重影响后果，运用预案研究方法和景观生态决策与评价支持系统( ledess )的决策与规划评价思想，对本区土地利用规划进行了以野生动物保护为核心的退耕预案设计，并对其生态后果进行了空间模拟和评价。 - The four scenarios , scenario no . l ( year 1988 ) , scenario no . 2 ( year 1998 ) , scenario no . 3 ( reed belt ) and scenario no . 4 ( habitat restoration ) , were different in the aims of ecological and economic benefit . and the habitat suitability , the breeding carrying capacity and the economic benefit of different scenarios on the wild animal habitat were simulated and evaluated . the conclusion showed that scenario no . l was unpractical because of the least economic benefit , scenario no . 2 had high economic benefit but low ecological benefit , which endangered the suitable habitats of the wild animals , and scenario no . 3 and scenario no . 4 should be the effective modes to keep harmonious development between economy and environment , which could be actualized as short - term and long term planning goals in the future
根据不同的经济和生态发展要求，对辽河三角洲大洼小三角洲的土地利用规划设计了四个预案，分别为88年原状(预案1 ) 、 98年原状(预案2 ) 、苇带设计(预案3 )和生境恢复(预案4 ) ，通过对各预案进行生境适宜性、生态承载力及经济效益评价，可以得到以下结论：预案1尽管生态效益很高，但经济效益很低，在区域发展需求下由现状年恢复到预案1具有不现实性；而预案2为强烈经济需求下，尤其是以粮食生产为主要目的的典型发展模式，生态效益偏低；预案3和预案4为生态与经济的协调发展模式提供了有效参考，短期内预案3的效果应该更好，但从长期来看，预案4应是更佳选择，可将其视为近期和远期规划目标分步实施。
