秦皇岛农业抗灾能力差,经常遭受旱、涝、风、雹灾害的袭击,年均受灾面积可达150万亩以上,年均成灾面积可达80万亩。其重要原因是因为森林面积小,覆被率低,对农业生产不能有效地发挥保护作用,对农业环境不能有效地发挥调节作用。因此,秦皇岛农业呼唤林业的保护。其一,农业需要森林为其维护和创造良好的生产环境。森林覆被状况是灾害性气象条件能否成灾的重要限制因素。科学家认为,一个地区森林覆被率达到30％,且分布均匀,就可以起到改善环境、维持生态平衡、限制灾害性气象条件成灾的作用。就山地丘陵区而言,则_森林覆被率应达到45％。秦皇岛地貌多山少林。全市山地面积广阔,达746.6
Qinhuangdao agricultural disaster resilience is poor, often suffer from drought, waterlogging, wind, hail disaster attacks, the annual affected area up to 1500000 mus of above, the average annual disaster area of 800000 mus. The important reason is that the forest area is small and the coverage rate is low, which can not effectively play a protective role in agricultural production and can not effectively regulate the agricultural environment. Therefore, Qinhuangdao agriculture calls for the protection of forestry. First, agriculture needs forests to maintain and create a good production environment for it. The status of forest cover is an important limiting factor to the disastrous meteorological conditions. Scientists believe that a region of 30% of the forest cover rate, and evenly distributed, you can play a role in improving the environment, maintaining the ecological balance and limiting disastrous meteorological conditions. In the case of mountainous hilly areas, the forest cover rate should reach 45%. Qinhuangdao mountainous Shaolin landscape. The city’s vast mountain area, up to 746.6
