Apart from land that was used for agriculture and fish farming, they also developed residential and industrial land. Fortunately, individual plants were not allowed to surpass 1000 hectares. And when it came to fish farms, they abided by the principle of using dikes but adding no fill. Since the dikes were not particularly high, their impact on the environment was limited.
在農漁業外，更擴增社區發展和工業區，所幸各單項計劃的開發面積多不超過 1,000 公頃，其中農漁業的開墾原則是只圍堤不填土，堤防也不高，對海岸自然環境影響有限。
