下图是我国黄淮海地区某地的土地利用现状图,读后回答问题。

根据图中信息可知,该地最容易发生的自然灾害是_______ ,判断理由是                                                           

                                                        。

除(1)灾害外,农业生产还受_________威胁,理由是________              

 (3) 为了有效地开发当地土地资源,拟在该地区建设一个新村庄。A、B、C、D四点中最合适的是_______点,理由是                                 

(4) 从可持续发展的角度,提出该地合理利用土地资源的措施。

答案

(1)洪涝   地势低平,河道弯曲,多沼泽,排水不畅

(2)盐碱   这里地势低洼,地表水丰富,但排水不畅,导致地下水位高,且华北地区晴天多,雨季短,尤其是春季,风大,干燥,蒸发强,易使土地盐碱化

(3)C  靠近农田和牧场,交通便利,利于生产和生活,地势相对较高,免受洪水威胁

(4)在低洼的沼泽地带发展水产养殖业,推行鱼塘-台田模式;在蔬林地和灌木林地发展经济林木
