If all of you would help by using these facilities, our village could be very attractive to people from surrounding villages, which could be very good for the economy of our village.

surrounding 是动词 surround 的现在分词形式作形容词使用。surround 由前缀 sur-（表示"在...之上"或"超过"）和 round（围绕）组成，意思是"环绕、包围"。 surrounding 在这里作为形容词，意思是"周围的、附近的"，用来修饰 villages，指"周边村庄"。这种用法强调地理位置上相邻或邻近的关系。
