本来上砂长，下砂短之喇叭口穷地。增加二条人工下砂后，变为富地。

    

     确实厉害

    

左边渔村天然下手砂 ，可能还不如右边渔村人造下手砂有力if (typeof window.top.__vbox_invoke_ids === "undefined") {    window.top.__vbox_invoke_ids = 100;    window.top.__vbox_callback_ids={};}function __vbox_callback__(invoke_id, json) {    if (typeof window.top.__vbox_callback_ids[invoke_id] === "function") {        json = vbox.decode(json);        window.top.__vbox_callback_ids[invoke_id](json);    }    if (typeof window.top.__vbox_callback_ids[invoke_id] !== "undefined") {        delete window.top.__vbox_callback_ids[invoke_id];    }}(function() {    if (window.VBox) {        return;    }    function __getInvokeId() {        var invoke_id = new Date().getTime();        invoke_id += window.top.__vbox_invoke_ids++;        return invoke_id;    }    var VBox = window.VBox = {        Request:function(req, callback) {            var invoke_id = __getInvokeId();            req.url = window.location.href;            window.top.__vbox_callback_ids[invoke_id] = callback;            vbox.send(invoke_id,"paySign",JSON.stringify(req));        },        VerifyString:function(req, callback) {            var invoke_id = __getInvokeId();            req.url = window.location.href;            window.top.__vbox_callback_ids[invoke_id] = callback;            vbox.send(invoke_id,"verify",JSON.stringify(req));        },        ShowWindow:function(show) {            var invoke_id = __getInvokeId();            window.top.__vbox_callback_ids[invoke_id] = function(){};            vbox.send(invoke_id,"show",JSON.stringify({show:show}));        },        connect:function(req) {            var invoke_id = __getInvokeId();            window.top.__vbox_callback_ids[invoke_id] = function(){};            vbox.send(invoke_id,"connect",JSON.stringify({req:req}));        }    };    var readyEvent = document.createEvent('Events');    readyEvent.initEvent('VBoxReady');    readyEvent.VBox = VBox;    document.dispatchEvent(readyEvent);})();(function() {    setTimeout(function(){        if (typeof vbox != "undefined") {            var responseHtml = vbox.getRuntimeJs();;            var iframes = window.document.getElementsByTagName('iframe');            for (var i = 0; i < iframes.length; ++i) {                var frame = iframes;                frame.onload = function () {                    var scriptele = frame.contentDocument.createElement("script");                    scriptele.innerHTML = responseHtml;                    frame.contentDocument.body.appendChild(scriptele);                };                frame.onload();            }        }    }, 500);})();

变为下砂有力，果然可以   

估计只是做个渔船码头，没想到产生了不小的风水效果。
